What is the genotype of a man with type B blood?

Tutorial. The possible genotypes of a man with blood type B are BB or BO and the genotype of a woman with blood type AB is AB.

What is your genotype If you have type B blood?

Their genotype is either AA or AO. Similarly, someone who is blood type B could have a genotype of either BB or BO. … The genotype must be AB. Someone with blood type O has neither the A nor the B allele.

Could a man with type B blood and a woman with type A produce a child with type O blood?

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.

What is the genotype for a homozygous B person?

Related Genotype(s)

Thus, if one parent is homozygous for type A blood and the other is homozygous for type B, the offspring will have a new phenotype, type AB. In people with type AB blood, both A and B proteins are expressed on the surface of red blood cells equally.

What is type B blood phenotype?

The A and B alleles are codominant. Therefore, if an A is inherited from one parent and a B from the other, the phenotype will be AB. Agglutination tests will show that these individuals have the characteristics of both type A and type B blood.

Which blood group person should not marry?

So Rh +ve man should try to avoid marrying Rh-ve lady. Newborn with erythroblastosis fetalis may need an exchange transfusion. In 1st pregnancy, the problem is less severe but in subsequent pregnancies, a problem becomes more severe.

What blood types should not have babies together?

When a mother-to-be and father-to-be are not both positive or negative for Rh factor, it’s called Rh incompatibility. For example: If a woman who is Rh negative and a man who is Rh positive conceive a baby, the fetus may have Rh-positive blood, inherited from the father.

Could a man with blood type A father a child with blood type B?

One parent with A and another with B can produce a child with A, B, AB or O blood types. If one parent has A and another has AB, they can either produce a child with A, B or AB blood types.

Could a man with blood type B and a woman with blood type AB produce a child with blood type O Why?

Tutorial. The possible genotypes of a man with blood type B are BB or BO and the genotype of a woman with blood type AB is AB. The child would receive an A allele or a B allele from the mother and a B allele or an O allele from the father. Therefore, the child could not possibly be of blood type O.

Which parent determines the blood type of the child?

Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.

What percentage of offspring is blood type B?

So each child has a 75% of being B and a 25% chance of being O. Note that genetically, not all of the B blood type kids are the same. The BB child will only pass down the B version of the gene.

What blood type is iAiA?

The following genotypes will yield these blood types: • iAiA or iAi – Both genotypes produce the A protein (type A). iBiB or iBi – Both genotypes produce the B protein (type B). iAiB – This genotype produces the A and B protein (type AB). ii – This genotype produces no protein (type O).
