Humans can have type A, B, AB, or O blood. A and B are codominant to each other and dominant to O. If a woman with type AB blood and a man with type O blood have a baby, what is the chance the baby will have type O blood?
0%
no- both parents could be heterozygous for their blood types
0%
9 red and small : 3 red and large : 3 black and small : 1 black and large
100% long and short mixed
50%
all of the plants will be tall and half will have wrinkled peas
25% red, 50% orange, 25% yellow
Humans can have type A, B, AB, or O blood. A and B are codominant to each other and dominant to O. If a woman with type A blood and a man with type B blood have a baby with type O blood, was the woman necessarily unfaithful (cheated)?
