Blood types A and B are codiminant and completely dominant to blood type O. A person with blood type AB has a child with a person with blood type O. What percent of their children are likely to express blood type O?

When you do the Punnett square of the couple (AB x OO), The blood would only be type A or B. The blood types dominate over blood type O since O is a recessive trait. So, blood type O would only possibly show if both parents have the trait.

The percentage of children that will likely express the blood type O is 0%. Details about genetic crosses can be found below.

What is co-dominance?

Co-dominance is condition in which both alleles of a gene pair in a heterozygote are fully expressed, with neither one being dominant or recessive to the other.

According to this question, blood types A and B are codiminant and completely dominant to blood type O.

This means that if a person with with blood type AB has a child with a person with blood type O, the offsprings of this cross will have the following genotype:

AO
BO

Therefore, the percentage of children that will likely express the blood type O is 0%.
