The gentotype is ii that will produce blood type O. The allele i is recessive, so both parents must have at least one i allele, and the child must be ii (double recessive) to be blood type O.
The parents' blood types do not have to be type O- the genotypes Ai (blood type A, as A is dominant), and Bi (blood type B) can produce blood type O offspring, as long as the child inherits the i allele.
The woman would have genotype AO (IAIA) for blood type A, the man would have genotype BO (IBIB) for blood type B, and their child with blood type O would have genotype OO (ii). The child inherited one O allele from each parent.
The woman would have blood type A. A genotype of IA indicates the presence of the A antigen on red blood cells.
There is only one possible blood genotype that gives group O. The person must be homozygous for type O.
Phenotypes are the traits expressed by the genotype. So, for blood type, a person can have A and i alleles (genotype). However, in the phenotype, since i is recessive, only the A will be expressed, and the person will have an A blood type.
Yes, a person with AO genotype can donate blood to a person with blood type O because type O can receive blood from A and O blood types. The A from the donor's blood will not cause a reaction with the recipient's O blood.
AB
If the father is homozygous for the B blood group, giving him the BB blood genotype, and the mother's genotype is AB (the only genotype for the AB blood group), then their offspring could have either the AB or B blood groups. If the father is heterozygous for the B blood group, giving him the BO genotype, then their offspring could have the AB, A, or B blood groups. However, they could not produce an offspring with the O blood group.
Phenotypes are the traits expressed by the genotype. So, for blood type, a person can have A and i alleles (genotype). However, in the phenotype, since i is recessive, only the A will be expressed, and the person will have an A blood type.
If one parent is O and the other is AB, the child can either be blood type A (genotype AO) or B (genotype BO).
If you have the genotype BO, you will have blood type B. This means you will produce B antigens. You will also produce Anti-A antibodies, meaning you cannot receive a transfusion of type A or AB blood.
Yes. There are two possible genotypes for a person with type B blood: BB or BO. If a person with the BB genotype has children with a person with type O blood, then all of their children will have type B blood. But, it the person has the BO genotype, then any child they have will have a 50% chance of having type O blood.
In the perfect world, no. IA and IB are codominant so both alleles are represented in the person's phenotype. Blood type A can only be represented by itself in a phenotype if the person's genotype is either IA IA or IA i.(The result of a DNA mutation may be able to create a phenotype of blood type A out of a (purebred) cross (of blood type A and B).No. IA and IB are both codominant . Blood type A can only be represented by itself in a phenotype if the person's genotype is IAIA or IAi. Blood type B can only be represented by itseft in a phenotype if the person's genotype is IBIB or IBi. If the phenotype (blood type) is AB the genotype is IAIB.
If both parents are genotype BB, the child can only be blood type B. The child's genotype would also be BB.
The woman would have genotype AO (IAIA) for blood type A, the man would have genotype BO (IBIB) for blood type B, and their child with blood type O would have genotype OO (ii). The child inherited one O allele from each parent.
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 woman would have blood type A. A genotype of IA indicates the presence of the A antigen on red blood cells.
Depending on their actual genotypes and which of those genes the offspring receive, their offspring might have AB, A, B, or O blood type. For the man to have a phenotype blood type A he might have either genotype AA or Ao. For the woman to have a phenotype blood type B she might have either genotype BB or Bo.
