Answer 1

• It is true that 2 parents that are heterozygous for type A blood could have offspring with type O.
• It is false that 2 parents that are type AB could have offspring that are type O.
• It is false that one parent who is type AB and one who is heterozygous type B could have offspring w/ type A, B, and O.

Blood that runs in a human body is categorized into 3 types namely the A, B and the O depending upon the blood in their parents. The O blood is recessive and thereby it gets expressed only if both the parents have O group.
