Question

which of the two sperm or egg decides the sex of the child​

Answer 1

Answer:

x chromosome and y chromosome

Answer 2

Sperm from the male sexual part decides the sex or gender of the child . Because female has 22+xx chromosome whereas male has 22+xy chromosome . It depends on the sperm of male whether he gives X or y . Therefore, sex of child is determined by males .

But in our society if a girl child born we curse female gender for this . Actually , those who do if don't have proper knowledge of science . In my language they are illiterate . Hope you all agree .
