The male fruit fly and female fowl are heterogametic while the female fruit fly and the male fowl are homogametic. Why are they called so? |
|
Answer» The male fruit fly has XY sex chromosomes and produces two types of gametes, hence it is called heterogametic while female fowl has ZW sex chromosomes thereby producing two types of gametes, thus it is called heterogametic. Female fruit fly has two X chromosomes, i.e., XX and produces similar gametes, hence it is called homogametic. Also, male fowl has two Z chromosomes and produces similar gametes, thus it is called homogametic. |
