Answer 2

Explanation:

there are 23,pairs of sex chromosomes in male and female, the 22 are same,but one is different,the male have xy chromosomes, while females have xx chromosomes, if the sperm which goes in vagina is y,then there is a possibility of a boy,if x goes there is possibility of a girl,the fact that the mother is responsible for the sex of the baby is absolutely wrong.
