There are 4 different blood types, these are the phenotypes: Blood type A, blood type B, blood type AB, and blood type O.
-The genotypes for type A blood are AA (homozygous) or AO (heterozygous), A is dominant, O is recessive.
-The genotype for type AB blood is AB. A and B are co-dominant, which means they both show.
-The genotypes for type B blood are BB (homozygous) or BO (heterozygous), B is dominant, O is recessive.
-The genotype for type O blood is OO. The only way to get a recessive trait is to have 2 copies of the recessive allele.
Cross a heterozygous type A parent with a heterozygous type B parent. What percent of the offspring are:
Type A: Type B: Type AB: Type O:
