What are all the possible blood types in a cross between a heterozygous Type A dad (IAi) and a heterozygous Type B (IBi) mom?
In this case, the possible blood types in the offspring can be determined by combining the various alleles inherited from the parents.
The father (IAi) can pass down either the IA allele (Type A) or the i allele (Type O) to the offspring.
The mother (IBi) can pass down either the IB allele (Type B) or the i allele (Type O) to the offspring.
Therefore, the possible combinations and resulting blood types are as follows:
1. IA IB: Type AB (Inherited both Type A and Type B alleles)
2. IA i: Type A (Inherited Type A allele from father and Type O allele from mother)
3. IB i: Type B (Inherited Type B allele from mother and Type O allele from father)
4. i i: Type O (Inherited Type O allele from both parents)
So, the possible blood types in the offspring are AB, A, B, and O.
