Question

A man with A blood group marries a woman with B blood group and both show the presence of homozygous alleles. The possible genotypes of the offsprings would be

I. Type $A$
II. Type $B$
III. Type $O$
IV. Type $AB$

• A. II only
• B. I and II
• C. I, II and IV
• D. I, II, III and IV
• E. IV only

Answer 1

The correct option is E IV only

Since both the parents show the presence of homozygous alleles( I${}^A$I${}^A$ and I${}^B$I${}^B$), on crossing the genotype of the offspring would be a heterozygote and of the type I${}^A$I${}^B$ and expressed as AB blood type.
