Answer 1

hey u buddy here yours answer
__________________________
The male fruit fly has XY sex chromosomes and produces two types of gametes. Hence, it is called heterogametic. A female fowl has ZW sex chromosomes, thereby producing two types of gametes. Hence, it is called heterogametic. The female fruit fly has two X chromosomes, i.e. XX and produces similar gametes. Hence, it is called homogametic. Also, the male fowl has two Z chromosomes and produces similar gametes. Therefore, it is called homogametic.

Answer 2

Fruit fly and fowl

Explanation:

This is because the male fruit fly and female fowl are with two heteromorphic (differently shaped) sex chromosomes XY(in case of male fruit fly); sex chromosomes in female fowl is represented by ZW

On the other hand, the female fruit fly and the male fowl are homgametic as they have two of the same kind of sex chromosomes XX(in case of female fruit fly); sex chromosomes in male fowl is represented by ZZ
