B.polygenic


C sex-linked


D. simple dominant

The blood types A,B,AB, and O are the results of _______ inheritance?
A.multiple allelic.


the gene for blood types has 3 alleles(not 2 as usual), A and B and O.


A and B are dominant to each other so AB blood group is found
Reply:I think it's sex-linked.
Reply:Multiple allelic, as mentioned above, however, A and B are not dominant to O. This is actually a co-dominance situation where the O allele codes for no antigens. And individual with an AO genotype has both alleles expressed, producing A antigens and no antigens respectively.
