Show why or why not with a Punnett square.

Answer 1

yes

Step-by-step 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

hope this helps :)

Answer 2

Yes, they can! With genotypes iAi x iBi, they will be able to create an ii which is type O
