Select the incorrect statement. A. In domesticated fowls, sex of progeny depends on the type of sperm rather than egg. B. Male fruit fly is heterogametic. C. Human males have one of their sex-chromosome much shorter than the other. D. In male grasshoppers50

In domesticated fowls, sex of progeny depends on the type of sperm rather than egg

Male fruit fly is heterogametic

Human males have one of their sex-chromosome much shorter than the other

In male grasshoppers50

Solution:

Correct option is C. In domesticated fowls, sex of progeny depends on the type of sperm rather than egg. Correct Option: C Explanation: Birds show ZZ-ZW type of sex determination, where male birds are homogametic (ZZ) and female birds are heterogametic (ZW). Sex chromosomes of birds are represented by ZZ-ZW. Since the female is heterogametic, the sex of progeny is determined by the type of egg rather than the sperm.
