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: -Two parents with A blood type can produce a child with either A or O blood types. Two parents with B blood type can produce a child with either B or O blood type.

Detailed explanation-5: -But it is technically possible for two O-type parents to have a child with A or B blood, and maybe even AB (although this is even more unlikely). In fact, a child can get almost any kind of blood type if you consider the rule-breaking exceptions.
