AP BIOLOGY

Detailed explanation-1: -Yes, it is possible that a father with an A-blood type and a mother with a B-blood type could have an offspring that has an O-blood type. The difference in blood type between parents and offspring is possible provided that both parents are heterozygous and carries the gene that codes for the O-blood type.

Detailed explanation-2: -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. One parent with A and another with B can produce a child with A, B, AB or O blood types.

Detailed explanation-3: -If a person of O blood group breeds with a person of B group all the children must be either B or O. If the child is A or AB one of the individuals cannot be the parent. An O and B crossing can not produce an A or AB child. An AB with an O can produce A children or B children but not O.

Detailed explanation-4: -Blood group AB is always heterozygous with the genotype IAIB and blood group O is always homozygous, and its genotype is represented as IOIO or ii.

Detailed explanation-5: -In general, does a child usually have the same blood type as one of their parent’s blood type? While a child could have the same blood type as one of his/her parents, it doesn’t always happen that way. For example, parents with AB and O blood types can either have children with blood type A or blood type B.
