Codominance is a form of inheritance in which two different alleles for a gene are both expressed, and neither allele is dominan
t 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.
