Select the incorrect statement.
Male fruit fly is heterogametic
In male grasshoppers 50% of sperms have no sex-chromosome
In domesticated fowls, sex of progeny depends on the type of sperm rather than egg
Human males have one of their sex-chromosome much shorter than the other
In birds female heterogamety is found thus sex of progeny depends on the types of egg rather than the type of sperm. Birds (fowls) male -> sperm = A + Z type (100%), female -> eggs = A + Z (50%) or A + W (50%).
