Consider the genetic cross for blood type of these two parents. The father is type A and the mother is type B. Both have the
recessive allele for blood type 0. What is the probability that these parents will have offspring with type A blood?
0%
10%
25%
50%

Hi There the correct answer to this is A. 0%

Explanation:

Two O parents will get an O child nearly all of the time. But it is technically possible for two O-type parents to have a child with A or B blood, and maybe even AB (although this is really unlikely). In fact, a child can get almost any kind of blood type if you consider the effect of mutations.
