AP BIOLOGY

Detailed explanation-1: -A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter. This couple could have children of either blood type A (O from mother and A from father) or blood type B (O from mother and B from father).

Detailed explanation-2: -Believe it or not, in this case having a blood type different from either parent is by far the most common result. In most cases, an O parent and an AB parent will have only A or B kids.

Detailed explanation-3: -Answer and Explanation: A man with type O blood would not be able to produce a child with type AB blood regardless of the mothers blood type. This is because type O blood is recessive and these individuals have two O alleles so the only allele they would be able to pass to a child would be “O".

Detailed explanation-4: -If a man with type AB blood marries a woman with type O, the children will have blood types A and B. Each blood type will be a fraction of ½. This is because ‘A’ and ‘B’ alleles are dominant alleles on ‘O’.

Detailed explanation-5: -For example, a man who has type AB blood could not father a child with type O blood, because he would pass on either the A or the B allele to all of his offspring.
