State Importance Of Chromosomal Difference Between Sperms And Eggs Of Humans

State the importance of chromosomal difference between sperms and eggs of humans.

Answers:

A male has XY chromosomes and a female has XX chromosomes. So, the sperms will have half X chromosomes and half y chromosomes.

1. If a sperm carrying X chromosome from male gets combined with the X chromosome from female, then the combination will be XX and child will be a baby girl.

2. If a sperm carrying Y chromosome from male gets combined with the X chromosome from female, then the combination will be XY, and the child will be a baby boy. So, the chromosomal difference between sperms and eggs of humans is responsible for determination of the sex of the child.
