Download to read the full article text. Normal male mammals have two copies of these genes: one in the pseudoautosomal region of their Y chromosome, the other in the corresponding portion of their X chromosome. Nature Education.
The stocks selected were such that they differed from each other significantly in respect of all the traits studied.
In fact the data showed that the contribution of the autosomes is more than that of the X-chromosome. The function of these pseudoautosomal regions is that they allow the X and Y chromosomes to pair and properly segregate during meiosis in males. Normal females also possess two copies of pseudoautosomal genes, as each of their two X chromosomes contains a pseudoautosomal region.

- A sex chromosome , also referred to as an allosome , heterotypical chromosome , or heterochromosome , [1] [2] or idiochromosome [3] 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.
- Autosome , any of the numbered or nonsex chromosomes of an organism. Humans have 22 sets of autosomes; they are referred to numerically e.
- An autosome is any of the numbered chromosomes, as opposed to the sex chromosomes. Humans have 22 pairs of autosomes and one pair of sex chromosomes the X and Y.
- During the cell division, chromatin in the nucleus shrinks to a thread like structures named chromosomes.
