Question

what is the probable genotypic ratio among children born to a mother having the genotype Iai and a father with type AB blood

Answer 1

Answer:

The genotype ratio would be 1:1:1:1

Explanation:

If a mother has the genotype Iai and a father having AB blood group is crossed than all four offspring would have different genotype.  

                           IA       IB

                     IA  IAIA    IAIB

                     i   IAi        IBi

So out of four offspring first have genotype  IAIA,  second have genotype  IAIB, third have genotype  IAi, and fourth have genotype IBi. Therefore the genotype ratio would be 1:1:1:1. Out of four offspring two would have A blood group, one would have AB blood group and one would and B blood group.
