How is the equal genetic contribution of male and female parents ensured in the progeny?

Explanation

In human beings, every somatic cell of the body contain 23 pairs are known as autosomes and the remaining one pair is known as sex chromosomes repesented as Xand Y Female have two X chromosomes and males have one Xand Y chromosome each. The gamete receives half of the chromosome. There fore the male gametes have 22 autosomes and either X or Y chromosome The female gamete, on the other hand, has 22autosomes and X chromosome During reproduction the male and female gametes fuse and thus progency receives 22 autosomes and one X or Y chromosomes from male parent and 22 autosomes and one X chromosomes from the female parent
