Solution :
In case of humans, the sex determining mechanism is XX-XY type. Out of 23 pairs of chromosomes, 22 pairs are exactly same in both males and females and are called ; autosomes. A pair of X chromosomes is present in the females, whereas the presence of an X and Y chromosomes is determinant of male characteristics.
