- What is the frequency of the aa genotype if the frequencies of AA & Aa are 0.1900 and 0.3600?The ABO blood groups in humans are expressed as the IAlB, and IAalleles. The allele encodes the A blood group antigen, lBencodes B, and i encodes O. Both A and B are dominant to O. If a heterozygous blood type A parent (IAi) and a heterozygous blood type B parent (IBi) mate, one quarter of their offspring will have AB blood type (IAIB) in which both antigens are expressed equally. Therefore, ABO blood groups are an example of: multiple alleles and incomplete dominance codominance and incomplete dominance incomplete dominance only multiple alleles and codominance1. There are two different variations at STR locus THO1. Where did these variations come from? b) The STR locus D21S11 only has one variation. Why?
