Can you justify the statement that “Human males are responsible for determining the sex of the baby and not females”?
The sex in human beings or the sex of the individual is largely genetically determined. A male cell has two types of sex chromosomes i.e., X – chromosome and Y – chromosome because of which male produces two types of sperms with genotype A + X and A + Y. Female cells have two X – chromosomes so the genotype of eggs produced by her is A + X. During fertilisation the chances are: If a sperm carrying Y – chromosome fertilises the egg, then the child born will be a male i.e., AA + XY. If a sperm carrying X – chromosome fertilises the egg then the child born will be a female i.e., AA + XX. Thus we can infer that the sperm of the male determines the sex of the child
