Will make brainliest help asap Human blood type is
determined by multiple alleles (A, B, and o) Which ratio would result from a cross between a man with heterozygous Type A blood and a woman with Type O blood?
50% Type A 50% Type O
50% Type AB 50% Type O
100% Type A
100% Type O

In this problem, there is no uncertainty abt the genotype of either parent. A parent of blood type AB has the co-dominant IA and IB alleles. A parent of blood type O is homózygous recessive for the i allele.

The Punnett square for their offspring is shown to the right. The genotypes of their offspring could be either IAi or IBi. Their children could be in blood groups A or B, but not AB or O.

Explanation:

Most-likely the third one.
