Assumptions in tests for meiotic drive.
Recent claims for the existence of meiotic drive in the ABO blood groups require the assumption of equal fertility (if there is no other selection operating) for the various mating types. There is evidence that does not support this assumption, and there are no convincing a priori grounds for making it.

Prezygotic selection in ABO blood groups.
A statistical method was devised to test whether prezygotic selection was operating in ABO blood groups, and it was demonstrated, with data from Japanese families, that heterozygous AO and BO fathers transmitted more than 50 percent O-bearing sperm (approximately 55 percent) to their children. Neither sperm incompatibility nor reproductive compensation could account for the results.
