The genetic architecture suggests that either the Y chromosome has an X-inactivating gene, or that the Y h chromosome has an X-activating gene.
Allosomes not only carry the genes that determine male and female traits, but also those for some other characteristics as well. Genes that are carried by either sex chromosome are said to be sex linked.
Sex linked diseases are passed down through families through one of the X or Y chromosomes. Since usually men inherit Y chromosomes, they are the only ones to inherit Y-linked traits. Men and women can get the X-linked ones since both inherit X chromosomes.
An allele is either said to be dominant or recessive.
Dominant inheritance occurs when an abnormal gene from one parent causes disease even though the matching gene from the other parent is normal. The abnormal allele dominates.
Recessive inheritance is when both matching genes must be abnormal to cause disease. If only one gene in the pair is abnormal, the disease does not occur, or is mild.
Someone who has one abnormal gene but no symptoms is called a carrier. A carrier can pass this abnormal gene to his or her children. Most of them code for something other than female anatomical traits. Many of the non-sex determining X-linked genes are responsible for abnormal conditions.
The Y chromosome carries about 78 genes. Most of the Y chromosome genes are involved with essential cell house-keeping activities and sperm production.
Only one of the Y chromosome genes, the SRY gene, is responsible for male anatomical traits. When any of the 9 genes involved in sperm production are missing or defective the result is usually very low sperm counts and infertility.

There are 2 sex chromosomes - X and Y. Females have 22 autosomes and two X chromosomes, i.e., 22 + XX, while males have 22 autosomes and an X and Y chromosome each, i.e., 22 + XY. This therefore proves that X is the female chromosome, and Y is the male chromosome. Why then, are men not YY? Does having an X chromosome make them only half men? It is commonly recognized that the Y chromosome determines male sex. Individuals develop as females by default without the Y chromosome. In mammals, the Mammalian females have two X chromosomes, while males have only one X plus a Y chromosome. In order to balance X-linked gene dosage between the sexes, one X chromosome undergoes inactivation during development of female embryos. This process has been termed X-chromosome

The XY sex-determination system is a sex-determination system used to classify many mammals, including humans, some insects , some snakes, some fish , and some plants (Ginkgo tree). In this system, the sex of an individual is determined by a pair of sex indiataazakhabar.coms have two of the same kind of sex chromosome (XX), and are called the homogametic sex A sex chromosome (also referred to as an allosome, heterotypical chromosome, gonosome, or heterochromosome, or idiochromosome) is a chromosome that differs from an ordinary autosome in form, size, and behavior. The human sex chromosomes, a typical pair of mammal allosomes, determine the sex of an individual created in sexual reproduction The X and Y chromosomes, also known as the sex chromosomes, determine the biological sex of an individual: females inherit an X chromosome from the father for a XX genotype, while males inherit a Y chromosome from the father for a XY genotype (mothers only pass on X chromosomes)

A man (pictured) possesses XY sex chromosomes and women have XX. The Y chromosome is important in reproduction but has little other function critical for life, as a result the chromosome has become The mammalian sex chromosome system (XX female/XY male) is ancient and highly conserved. The sex chromosome karyotype of the creeping vole (Microtus oregoni) represents a long-standing anomaly, with an X chromosome that is unpaired in females (X0) and exclusively maternally indiataazakhabar.com: Matthew B. Couger, Scott W. Roy, Scott W. Roy, Noelle Anderson, Landen Gozashti, Stacy Pirro, Lindsa A sex chromosome is a type of chromosome that participates in sex determination. Humans and most other mammals have two sex chromosomes, the X and the Y. Females have two X chromosomes in their cells, while males have both X and a Y chromosomes in their cells. Egg cells all contain an X chromosome, while sperm cells contain an X or Y chromosome

And researchers think it is quickly disappearing. But the Y chromosome hasn't always been so small. The problem, however, is that Y chromosomes are only ever found as a single copy, passed from fathers to their sons, rather than a pair This means that genes on the Y chromosome cannot undergo something known as 'genetic recombination'.
