Question

homework - non-mendelian genetics
what would be (a) possible genotype(s) of an individual with type a blood?
aa only
aa or ao
ao only
aa or ab
aa or oo

Explanation:

In human blood types, the \(I^A\) allele (for Type A) is dominant over the \(O\) allele (\(i\)). So, an individual with Type A blood can have two genotypes. If they have two \(I^A\) alleles (\(AA\)), they are homozygous for Type A. If they have one \(I^A\) allele and one \(O\) allele (\(AO\)), the \(I^A\) allele's dominance results in Type A blood. The \(AB\) genotype gives Type AB blood, and \(OO\) gives Type O blood.

Answer:

AA or AO
