Can a mother with type A blood and a father with type B blood have a baby with type O blood?
Show why or why not with a Punnett square.

yes

Explanation:

type A and type B blood is a dominant trait, while type O is a recessive trait, so if a person has, for example, one gene for type O and another gene for type A, the person will have Type A blood.

it is possible that the Mother has the genes for both type A and Type O blood, but only shows the Type A. the same case with the father, except he has a copy of the type O and type B gene.

          B              O

A       AB            AO

O      BO            OO
