Which genotype would a person have who is homozygous type B?

Blood Type Related Genotype(s)
B BB or BO
AB AB
O OO

What is the genotype for someone who is type B homozygous?

The A and B alleles are dominant to the O allele. When both inherited alleles are O, the genotype is homozygous recessive and the blood type is O. When one of the inherited alleles is A and the other is B, the genotype is heterozygous and the blood type is AB. … Type B: The genotype is either BB or BO.

What genotype is type B?

Similarly, someone who is blood type B could have a genotype of either BB or BO. A blood test of either type AB or type O is more informative. Someone with blood type AB must have both the A and B alleles. The genotype must be AB.

What is homozygous for B?

An individual that contains two different alleles of a gene is heterozygous. Examples. A cow that has two alleles for a red coat is homozygous (bb). A bull with two alleles for a black coat is homozygous (BB).

What is heterozygous type B?

Heterozygous means one dominant & one recessive allele. Since they are Type “B”, the dominant allele is IB, & the only recessive allele for blood type is “i”.

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.

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.

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.

Can parents with A and B blood type have an O baby?

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

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.

Is BB homozygous dominant?

An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype.

Is AA homozygous or heterozygous?

Two dominant alleles (AA) or two recessive alleles (aa) are homozygous. One dominant allele and one recessive allele (Aa) is heterozygous.
