Sex Determination: More Complicated Than You Thought
 
05:46
From something as small and complex as a chromosome to something as seemingly simple as the weather, sex determination systems vary significantly across the animal kingdom. Biologist and teacher Aaron Reedy shows us the amazing differences between species when it comes to determination of gender. Lesson by Aaron Reedy, animation by BuzzCo (http://buzzzco.com).

Chromosomes are thread like structures that are present in nucleus of a eukaryotic cell, in case of prokaryotic cell they found in the cell cytoplasm in the circular form. Sex chromosomes mainly determine the type of gender an individual will have. There are significant differences between the sex chromosomes which had been listed in the video.

Genetic Inheritance - Sex Determination
 
03:56
CBSE class 10 Science - Heredity and Evolution - In human beings, the sex of new born is determined genetically, but in some animals, sex is determined on the environmental conditions. Number of chromosomes in humans = 46 23 comes from male parent and 23 comes from female parent, so there are 23 pair of chromosomes in which 22 are perfectly paired and one pair of chromosome is sex chromosome. The sex chromosomes are perfectly paired in females and have both X chromosomes whereas in males it is XY chromosome which is not perfectly paired. So through punnet square we will find out there are 50% chance of a female progeny and 50% chance of male progeny.

Sperm and Eggs Cells | Biology for All | FuseSchool
 
04:32
In this video we learn about the distinct differences of egg and sperm cells, which are also known as gametes. We will see how the chromosomes from each cells come together to form our unique genetic code. The gametes (sperm and egg cells) are haploid - so only have half the number of chromosomes. This is 23 in humans. When a sperm fertilises an egg cell, the chromosome number becomes diploid - so the normal number of chromosomes which is 46 in humans (found in 23 pairs). One chromosome in each pair comes from the mother and the other from the father. SUBSCRIBE to the FuseSchool YouTube channel for many more educational videos.

View full lesson: http://ed.ted.com/lessons/secrets-of-the-x-chromosome-robin-ball The sequence of DNA that we inherit from our parents encodes directions for making our cells and giving us specific traits. Identical twins have the same DNA sequence, so how can one twin end up with a genetic disorder while the other twin does not? Robin Ball explains how the secret lies in X chromosome inactivation.

Explore inheritance when carried on the X chromosome with the Amoeba Sisters! This video has a handout here: http://www.amoebasisters.com/handouts.html This video focuses on how to do general Punnett square problems that involve traits on the sex chromosomes (X and Y chromosomes). We do want to point out though that when it comes to biological sex- it can be influenced by more than just sex chromosomes X and Y. For example, the SRY gene, plays a major role in human biological sex determination. While this video only focuses on solving sex-linked trait problems in a Punnett square, here are some further reading suggestions to learn about the SRY gene and its role in biological sex.

4.2.7 Analyze a human karyotype to determine gender and whether non-disjunction has occurred
 
02:19
XX = female XY = male If all chromosome are in their homologous pairs (no extra chromosomes present; 2n) then non-disjunction has not occurred and there are no chromosomal abnormalities. Trisomy 21 shows non-disjunction has occurred for pair number 21, this results in Down syndrome. These individuals can be male (XY) or female (XX). XO shows non-disjunction has occurred for the sex chromosomes, this results in Turner syndrome. These individuals are genetically female. XXY shows non-disjunction has occurred for the sex chromosomes, this results in Kleinfelter syndrome. These individuals are genetically male.

جنس المولود the sex of ababy.wmv
 
06:28
Until fairly recently, it was thought that a baby's sex was determined by the mother's cells. Or at least, it was believed that the sex was determined by the male and female cells together. But we are given different information in the Qur'an, where it is stated that masculinity or femininity is created out of "a drop of sperm which has been ejected". "He has created both sexes, male and female from a drop of semen which has been ejected." (The Qur'an, 53:45-46) The developing disciplines of genetics and molecular biology have scientifically validated the accuracy of this information given by the Qur'an. It is now understood that sex is determined by the sperm cells from the male, and that the female has no role in this process. Chromosomes are the main elements in determining sex. Two of the 46 chromosomes that determine the structure of a human being are identified as the sex chromosomes. These two chromosomes are called "XY" in males, and "XX" in females, because the shapes of the chromosomes resemble these letters. The Y chromosome carries the genes that code for masculinity, while the X chromosome carries the genes that code for femininity. The formation of a new human being begins with the cross combination of one of these chromosomes, which exist in males and females in pairs. In females, both components of the sex cell, which divides into two during ovulation, carry X chromosomes. The sex cell of a male, on the other hand, produces two different kinds of sperm, one that contains X chromosomes and the other Y chromosomes. If an X chromosome from the female unites with a sperm that contains an X chromosome, then the baby is female. If it unites with the sperm that contains a Y chromosome, the baby is male. In other words, a baby's sex is determined by which chromosome from the male unites with the female's ovum. None of this was known until the discovery of genetics in the 20th century. Indeed, in many cultures, it was believed that a baby's sex was determined by the female's body. That was why women were blamed when they gave birth to girls. Thirteen centuries before human genes were discovered, however, the Qur'an revealed information that denies this superstition, and referred to the origin of sex lying not with women, but with the semen coming from men.

Genetics part 6 sex linkage (sex linked inheritance)
 
19:33
For more information, log on to- http://shomusbiology.weebly.com/ Download the study materials here- http://shomusbiology.weebly.com/bio-materials.html Sex linkage is the phenotypic expression of an allele related to the chromosomal sex of the individual. This mode of inheritance is in contrast to the inheritance of traits on autosomal chromosomes, where both sexes have the same probability of inheritance. Since humans have many more genes on the X than the Y, there are many more X-linked traits than Y-linked traits. In mammals, the female is the homogametic sex, with two X chromosomes (XX), while the male is heterogametic, with one X and one Y chromosome (XY). Genes on the X or Y chromosome are called sex-linked. In birds, the opposite is true: the male is the homogametic sex, having two Z chromosomes (ZZ), and the female (hen) is heterogametic, having one Z and one W chromosome (ZW). X-linked recessive traits are expressed in all heterogametics, but are only expressed in those homogametics that are homozygous for the recessive allele. For example, an X-linked recessive allele in humans causes hemophilia. Hemophilia is much more common in males than females because males are hemizygous - they only have one copy of the gene in question - and therefore express the trait when they inherit one mutant allele. In contrast, a female must inherit two mutant alleles, a less frequent event since the mutant allele is rare in the population. Tsarevich Alexei of Russia was the most famous sufferer of X-linked hemophilia. The incidence of recessive X-linked phenotypes in females is the square of that in males (squaring a proportion less than one gives an outcome closer to 0 than the original). If 1 in 20 males in a human population are red-green color blind, then 1 in 400 females in the population are expected to be color-blind (1/20)*(1/20). (The term 'color-blind' is not completely accurate. There are degrees of weakness in color vision and it is now called 'color vision deficiency') X-linked traits are maternally inherited from carrier mothers or from an affected father. Each son born to a carrier mother has a 50% probability of inheriting the X-chromosome carrying the mutant allele. There are a few Y-linked traits; these are inherited from the father.

Diploid vs. Haploid Cells
 
08:31
In this video Paul Andersen explains the difference between diploid and haploid cells. He starts with a brief description of the central dogma and how genes code for proteins. He then uses the phenotype of red hair to explain that humans are diploid creatures. He discriminates between diploid somatic cells and haploid sex cells. He finishes with a brief description of different life cycles dominated by haploid and diploid individuals.

Chromosomal Abnormalities and Non-Disjunction

NOTE! The label for "sister chromatids" at 1:30 should say "homologous chromosomes"! Sadly, Youtube deleted the "annotations" feature that had previously corrected the error. Thanks for the viewers who noticed the problem! Chromosomal problems can easily occur during reproduction. Continuing our discussion of reproduction, this screencast concerns common chromosomal abnormalities, specifically non-disjunction. During nondisjunction, an incorrect number of chromosomes are allocated into the resulting sex cells.

Autosomal and X Linked Inheritance
 
11:12
This lecture explains about the the autosomal and x linked inheritance. This video explains the properties of sex linked inheritance and the genetics pedigree. Autosomal trait is the one where the gene responsible for the trait is carried by Autosomes or body cell chromosomes. Sex linked trait or X linked trait is the one where the gene responsible for the trait is carried by X chromosomes. So most of the X linked trait is predominant ion male as males have only one X chromosome.

X Inactivation and Epigenetics
 
11:04
X inactivation is a vital process that occurs in all DNA-containing cells of the female body. It is also an important research model and tool for studying epigenetics. Epigenetics refers to processes that tell our cells how, and when, to read the DNA blueprint. The epigenetic regulation of DNA is critical in both normal development and disease. X inactivation is a type of gene dosage compensation. In humans, the sex chromosomes X and Y determine the sex of an individual - females have two X chromosomes (XX), males have one X and one Y chromosome (XY). All of the genes on the Y chromosome are required in male development, while the genes on the X chromosome are needed for both male and female development. Because females receive two X chromosomes, they inherit two copies of many of the genes that are needed for normal function. Extra copies of genes or chromosomes can affect normal development. An example is Down's syndrome, which is caused by an extra copy of part or all of chromosome 21. In female mammals, a process called X inactivation has evolved to compensate for the extra X chromosome. In X inactivation, each cell 'switches off' one of its X chromosomes, chosen at random, to ensure the correct number of genes are expressed, and to prevent abnormal development.

Geneticists Study Jesus’ Blood - 24 Chromosomes and ‘Non Human’
 
03:58
A team of research scientists in Tel Aviv did a genetic analysis from a blood sample widely believed to have belonged to Jesus, concluding that Jesus’ biological father was ‘non-human’. This video is audio of a press conference with archaeologist Ron Wyatt. Having 24 distinct chromosomes or 22 autosomes (mother's are duplicated) in addition to 2 (XY) chromosomes, the 22 autosomes of the mother are equal to the corresponding 22 autosomes of the father (one to one) and the X chromosome of the mother (XX) plus the "Y" sex chromosome given by father being (XY). In total, 2 of His mother's autosomal chromosomes duplicated times 22, plus 1 (X) chromosome + 1 (Y) chromosome = 23 homologous pairs of chromosomes. Thus, the (Heavenly) Father's (Y) male chromosome was expressed as Jesus. The DNA Jesus is 96% from Mary rather than 50% from Mary as would be normal. So the Holy Spirit had to have inseminated a virginal Mary with the "Y" chromosome of the one true almighty G-d of Abraham.

Nettie Stevens discovered XY sex chromosomes

http://topinsurancehealth.com/nettie-stevens-discovered-xy-sex-chromosomes-she-didnt-get-credit-because-she-had-two-xs/ Nettie Stevens discovered XY sex chromosomes. She didn't get credit because she had two X’s. At the turn of the 20th century, biologist Nettie Stevens was driven to solve a scientific mystery that had perplexed humanity for millennia. The mystery was so simple but daunting: Why do boys become boys and girls become girls? In her pioneering work at Bryn Mawr College, Stevens discovered the sex chromosomes that make the difference. Before Stevens, we were utterly clueless about how embryos become boys or girls Thanks to Stevens’s work — and the work that built upon it — we now know that sex is hereditary, and that dads’ sperm in particular determine the sex of offspring. But for most of human history, this question was an absolute mystery — and it yielded some interesting theories. Aristotle believed a child’s sex was determined by the body temperature of the father during sex. “Aristotle counseled elderly men to conceive in the summer if they wished to have male heirs,” the textbook Developmental Biology explains.

So, sex, how does it work?

God Said Jesus is His Son (So Does Jesus' DNA)
 
02:34
God said that Jesus is His son, and, according to scientists, so does Jesus' DNA. When scientists tested the dried, two-thousand-year-old "dead" blood, to their shock, they were able to analyze its chromosomes—which is only possible with living blood. Having 24 distinct chromosomes or 22 autosomes (mother's are duplicated) in addition to 2 (XY) chromosomes, the 22 autosomes of the mother are equal to the corresponding 22 autosomes of the father (one to one) and the X chromosome of the mother (XX) plus the "Y" sex chromosome given by father being (XY). In total, 2 of His mother's autosomal chromosomes duplicated times 22, plus 1 (X) chromosome + 1 (Y) chromosome = 23 homologous pairs of chromosomes. Thus, His (Heavenly) Father's (Y) male chromosome determined only Jesus’ maleness, while His physical characteristics would have been determined solely by His Mother. Human cells normally have 46 chromosomes. These are actually 23 pairs of homologous chromosomes. In each pair of chromosomes, one of the pair is from the mother and the other member is from the father. Therefore, 23 chromosomes come from the mother and 23 from the father. In each set of 23, 22 chromosomes are autosomal and one is sex-determining. The sex-determining ones are the X chromosome and the Y chromosome. Females are XX, so they can only contribute an X chromosome to their offspring, whereas males are XY, which allows them to contribute either an X or a Y. If they contribute an X, the child is female, whereas if they contribute a Y, the child is male. The fascinating finding in this blood was that instead of 46 chromosomes, there were only 24. There were 22 autosomal chromosomes, one X chromosome and one Y chromosome. This evidences that the person to whom this blood belonged to had a mother but no human father, because the normal contribution of paternal chromosomes is missing. The DNA of Jesus is 96% from Mary rather than 50% from Mary as would be normal. So, theoretically, the Holy Spirit had to have inseminated a virginal Mary with the "Y" chromosome of the non-human God of Abraham. True believers don’t need proof, but in lieu of the scientific evidence, it should be clear to unbelievers that Jesus Christ is the genetic offspring of the God of Abraham. The precious blood of Jesus is just another confirmation and more evidence and proof of the reality of God's loving sacrifice of His own son for the sake of our sins. Three days after Jesus died, the Lord God of Israel resurrected and glorified him (made Him immortal through the power of the Holy Spirit). Lord Jesus is clearly the Son of YHVH and our prophesied Messiah. We eagerly await the Second Coming of our King!
