Ahomozygous type b woman marries a heterozygous type a man. show punnett square genotypes and phenotype

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
