Question

Codominance is a form of inheritance in which two different alleles for a gene are both expressed, and neither allele is dominant over the other. One example of codominance is blood type in humans; the alleles for type A blood and type B blood are codominant. If a man who is homozygous for type A blood and a woman who is homozygous for type B blood have children, what would you expect to find in the children?
Half will have type A and half will have type B blood.
The children will all have type B blood.
The children will all have type AB blood.
The children will all have type A blood.

Answer 1

Answer:

Option C, The children will all have type AB blood.

Explanation:

In co dominance , both the alleles are dominant and are expressed equally without dominating each other.

A homozygous man for type A blood will have genotype AA

A homozygous woman for type B blood will have genotype BB

When homozygous man for type A blood and homozygous woman for type B blood are crossed , then following offspring are produced -

AA * BB

AB, AB, AB, AB

Hence, option C is correct

Answer 2

The to your question  answer is AB
