A woman with Type O blood and a man who is Type AB have are expecting a child. What are the possible blood types of the kid? 2. What are the possible blood types of a child who's parents are both heterozygous for "B" blood type?

Answers

Answer 1
Answer:

The possible blood type of offspring, when a woman with type O and a man who is type AB are expecting a child are A and B.

What are the types of blood groups?

There are four kinds of blood groups which are A, B, AB, and O, based on the presence of antigens in RBC. Blood groups A and B show co-dominance, while O is recessive.

When a woman with type O blood and a man who is Type AB are expecting a child, the possible blood types are A and B. 50% of the children would have A blood type, and 50% of children would have blood type B, which are heterozygous.

When Parents are both heterozygous for the B blood group, then the possible blood group of offspring would be 75% B blood type (25% are homozygous and 50% are heterozygous) and 25% O blood type.
