Phenotype is Type A: Type B
Genotype is 1:1
Explanation:
It is given that type B woman is homozygous.
Thus the genotype of the woman can be BB or bb
The man is of type A and heterozygous.
Thus the genotype of the man is Bb
We see that when the genotype is heterozygous Bb then the gene expresses type A condition
So, when the alleles are in homozygous dominant condition then the gene BB will also express in type A condition.
But we know that the women is type B. So, the genotype of the women is bb.
Cross between bb X Bb is shown in the punnett square attached
Thus,
Phenotype is Type A: Type B
Genotype is 1:1
