father and mother together determine the sex of the new born baby
in the process of copulation father sperm cells fuses with mother eggs or ovum
father has XY chromosome and mother has XX chromosome
due the medal law of segregation both chromatid has equal right to segregate independently
it is simple when mother 's x chromosome fuse with x chromosome of father
the baby born as a girl child
and if x chromosome of mother fuses with y chromosome of father the new born baby be determined as boy
-thanks

Explanation:
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.
The gametes, as we know, receive half of the chromosomes. The male gametes have 22 autosomes and either X or Y sex chromosome.
Type of male gametes: 22+X OR 22+ Y.
However, since the females have XX sex chromosomes, their gametes can only have X sex chromosome.
Type of female gamete: 22+X
Sex Detrmination in human beings
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.
