Answer 2

Answer:

The answer is

a) 25% chance of having O type blood

b) 25% chance of having AB type blood

Explanation:

Joe has blood group A

therefore he might have iAiA allele on his genes or iAiO allele on his genes

iA, iB is dominant over iO allele

since his father has type O blood group and his alleles must be iOiO therefore he his son Joe allele must have iAiO allele

therefore, the gametes of Joe will be

iA , iO

Now Mary has B blood group

therefore she might have iBiO allele on her genes

therefore the gametes of Mary will be iB,iB

or iB,iO

Now we can see the punnet square in image.
