Question

1. Male fruit fly is heterogametic. 2. In male grasshoppers, 50% of sperms have no sex-chromosome. 3. In domesticated fowls, sex of progeny depends on the type of sperm rather than egg. 4. Human males have one of their sex-chromosome much shorter than the other.

Doubtly AI · Accepted Answer

Answer: 3. In domesticated fowls, sex of progeny depends on the type of sperm rather than egg. We look for the incorrect statement. Male fruit fly is XY, heterogametic: correct. Male grasshopper is XO, so half the sperms have no sex chromosome: correct. Human Y is much shorter than X: correct. In fowls the system is ZW, with female heterogametic (ZW). The sex of the progeny depends on the egg (Z or W), not the sperm. So statement 3 is incorrect. Option 3 is the answer.
