How and where x and y chromosomes are produced in human male and female body?

Answer 1

X and Y chromosomes, just like any other chromosomes, lay in every cell in the human body that have a nucleus. In a male's generic cell there are 22 pairs of chromosomes, and X and Y. In a female's generic cell there are 23 pairs, one of which is XX.

In sex cells, however, there are only 23 chromosomes as opposed to the 46 in a normal cell. A sperm cell carries either one of the X and Y chromosome, while an egg carries the X chromosome. In a successful fertilisation these cells fuse and the result carries either XX or XY, determining a female or a male, respectfully.

Answer 2

In human males, both x and y chromosomes are produced in the testes through a process called spermatogenesis. In females, only x chromosomes are produced in the ovaries through oogenesis. The presence of x or y chromosomes determines the biological sex of an individual.
