We can call these alleles. Each of us has two ABO blood type alleles, because we each inherit one blood type allele from our biological mother and one from our biological father.
BBkk as there is no other alleles present for the man to inherit. the father can only pass on a B allele and a k allele and the mother can also only pass on a B allele and a k allele.
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.
Both. A genotype is the scientific part, the lettering. For example; Lets say the mother's face shape, being recessive, is represented by lower case (s), and the father's, being dominate, is represented by captial (S). So the genotype for this sidtuation is Ss The phenotype is the physical appearance of the trait.
In this case neither Pete nor Jack can be the father. A baby inherits one allele from each of its parents. This means that it will receive one G or g and one B or b from each parent. If Pete only has gb gametes - (meaning his genotype is ggbb) - then it is not possible for him to give a B to the baby. The same goes for Jack, whose gametes are Gb (meaning his genotype is GGbb). Neither of these men have a B - which means that they cannot be the father. The father would have to have BB or Bb for his child to have the genotype BB.
In this case, the mother does not have dimples (Dd) but the father does not have dimples (dd). The Punnett square would show that half of the offspring would have dimples (Dd) and the other half would not have dimples (dd).
heredity
The genotype of the father is certainly OO (because blood type O is recessive). The genotype of the mother however can be AO or AA (both give blood type A). The baby will have a combination of the genes from the mother and the father (one of each) and so: - If the genotype of the mother is AA and the genotype of the father is OO, the baby will certainly have AO as genotype and has therefore blood type A. -If the genotype of the mother is AO and the genotype of the father is OO, the baby can have AO or OO as genotype. AO results in blood type A and OO in blood type O (50% chance).
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.

50% AA and 50% Aa
The genotype of the father is certainly OO (because blood type O is recessive). The genotype of the mother however can be AO or AA (both give blood type A). The baby will have a combination of the genes from the mother and the father (one of each) and so: - If the genotype of the mother is AA and the genotype of the father is OO, the baby will certainly have AO as genotype and has therefore blood type A. -If the genotype of the mother is AO and the genotype of the father is OO, the baby can have AO or OO as genotype. AO results in blood type A and OO in blood type O (50% chance).
The mother will produce two types of gametes: IA and IO (mother is A) The father is AB his genotype is IAIB, thus he will produce these kind of gametes: IA and IB Four combinations are possible IA from Mother and IA from Father: The child has genotype IAIA and he has blood group A IO from Mother and IA from Father: The child has genotype IAIO and he has blood group A IA from Mother and IB from Father: The child has genotype IAIB and he has blood group AB IO from Mother and IB from Father: The child has genotype IBIO and he has blood group B Thus the phnotypic ratio is blood group A:B:AB = 2:1:1
It is not possible. NO
A genotype is decided from two alleles. One of these alleles comes from the father, and one comes from the mother. Thus it should be clear that the genotype can be different from both parents. For instance, suppose the father has genotype AA, and the mother has genotype aa. In this case, the child will have genotype Aa, which neither parent has.
depends... were they homozygous or heterozygous?
The mother would have to be type A. Father has genotype (0,0) Mother would need to have genotype (A,0) - fenotype (blood group) = A
