Question

State whether the following statement is true or false.

In chickens, the female is the homogametic sex.

Answer 1

This statement is false.

Explanation:

In chickens (and other birds), sex determination follows the ZW system, where the female is the heterogametic sex (ZW), producing two types of eggs containing either a Z or a W chromosome. The male is homogametic (ZZ), producing only one type of sperm with a Z chromosome. Thus, unlike humans where females are homogametic (XX), in chickens females are heterogametic and males are homogametic.
