Answer:

In human beings, the females have two X chromosomes and the males have one X and one Y chromosome. Therefore, the females are XX and the males are XY. ... Thus, the mother provides only X chromosomes. The sex of the baby is determined by the type of male gamete (X or Y) that fuses with the X chromosome of the female.

Sex is determined at the time of fertilisation. A human male has XY sex chromosome and produces two types of sperms, either with X chromosome or with a Y chromosome.

A human female has XX chromosome and produces ova of one type. If the sperm containing X chromosome fuses with ovum, the individual will be a girl and the sperm containing Y chromosome fuses with ovum, the individual will be a boy.

Thus, the sex of the individual is genetically determined.
