There is a 25% chance of the child being AA or BB, and a 50% chance of the child being AB.
If one parent is O and the other is AB, the child can either be blood type A (genotype AO) or B (genotype BO).
Yes D = Rh+, d = Rh- If both parents are heterozygous (D d), then the baby can get d from each; therefore, resulting in Rh- Also can get D from 1 parent & d from other parent resulting in Rh+ Or can get D from each parent, resulting in Rh+ As for B & AB, The parent which is type B has genotype of BO or BB both of which would result in B type. AB parent has only 1 option for genotype, AB The baby gets 1 gene from each parent, so possibilities for baby are: AB, B (genotype BO or BB; B is dominant), A (genotype AO; A is dominant) This baby could be type A+ A- B+ B- AB+ or AB-
If all the children are AB, then one parent is AA and the other is BB.
No probability. Neither parent has an "A" for the child to inherit to make an "AB".
The mother is genotype AB, the father is either genotype BO or BB. If the father is genotype BO, the children can be genotype AB, AO, BB, or BO. This results in children with phenotype blood types of: AB, A, or B. If the father is genotype BB, the children can be genotype AB, AB, BB, or BB. This results in children with phenotype blood types of: AB or B.
The mother is genotype AB, the father is either genotype BO or BB. If the father is genotype BO, the children can be genotype AB, AO, BB, or BO. This results in children with phenotype blood types of: AB, A, or B. If the father is genotype BB, the children can be genotype AB, AB, BB, or BB. This results in children with phenotype blood types of: AB or B.
The other parent could have a genotype of either AB or B. Blood type B is a result of having a genotype of either BB or BO. Therefore, the other parent could have a genotype of AB which results in blood type AB when paired with the child's B blood type, or blood type B if the other parent has a genotype of BO.
The blood type A is determined by having either two A alleles (genotype AA) or one A and one O allele (genotype AO). In this case, since the parents have blood types AB and A, they can only pass on an A allele or a B allele to their child. If the parents have a daughter with blood type A, it means they both contributed an A allele, as the daughter cannot have a B allele since her blood type is A. So, the genotype of the daughter is AO. Now, if we consider Baby Y, we can infer that Baby Y could inherit one A allele from one parent (let's say from the parent with blood type A) and one A allele or one B allele from the other parent (the parent with blood type AB). Therefore, Baby Y's genotype could be either AA or AB.
The mother is genotype AB, the father is either genotype BO or BB. If the father is genotype BO, the children can be genotype AB, AO, BB, or BO. This results in children with phenotype blood types of: AB, A, or B. If the father is genotype BB, the children can be genotype AB, AB, BB, or BB. This results in children with phenotype blood types of: AB or B.
AB
If one parent is B+ and the other parent is AB +, the child could be any blood type except type O. If the genotype of the parent with phenotype B is known, more detail could be given.
The parents have the following genotypes:Type B = genotype BB or BOType O = genotype OOType A = genotype AA or BOFor the appropriate crosses: BB/BO x OO = Baby Type BO or OOAA/AO x BB/BO = Baby Type AB, AO, OO
