Question

Males are heterogametic.why?

Answer 1

Heterogametic sex (digametic sex) refers to the sex of a species in which the sex chromosomes are not the same. For example, in humans, males, with an X and a Y sex chromosome, would be referred to as the heterogametic sex, and females having two X sex chromosomes would be referred to as the homogametic sex.

Answer 2

Because males are X AND Y hence are called heterogametic.
whereas as Females have X AND X they are termed as homogametic.
