Heterozygous means one dominant & one recessive allele. Since they are Type “
B
“, the dominant allele
Is blood type AB heterozygous or homozygous?

What is the genotype for heterozygous type A blood?
When one of the inherited alleles is A and the other is B, the genotype is heterozygous and the blood type is
AB
. AB blood type is an example of co-dominance since both traits are expressed equally. Type A: The genotype is either AA or AO.
What is the genotype of blood type A?
If someone has blood type A, they must have at least one copy of the A allele, but they could have two copies. Their genotype is either
AA or AO
. 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.
What are the odds that they will have a child with homozygous type A blood?

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).
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.
How do you know if you are heterozygous or homozygous?
If an organism has identical genes on both chromosomes, it is said to be
homozygous
. If the organism has two different alleles of the gene it is said to be heterozygous.
Is AA heterozygous or homozygous?
Two dominant alleles (AA) or two recessive alleles
(aa) are homozygous
. One dominant allele and one recessive allele (Aa) is heterozygous.
What is the difference between heterozygous and homozygous?
Heterozygous refers to having inherited different forms of a particular gene from each parent. A heterozygous genotype stands in contrast to
a homozygous genotype
, where an individual inherits identical forms of a particular gene from each parent.
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.
Which blood group 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 blood type A and B make O?
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 healthiest blood type?
People with type O blood have the lowest risk of heart disease while people with
B and AB
have the highest. People with A and AB blood have the highest rates of stomach cancer.
What blood type is rarest?
What’s the rarest blood type?
AB negative
is the rarest of the eight main blood types – just 1% of our donors have it. Despite being rare, demand for AB negative blood is low and we don’t struggle to find donors with AB negative blood.
Can O+ and O have a baby?
That means each child of these parents has a 1 in 8 chance to have a baby with an O- blood type. Each of their kids will also have a 3 in 8 chance of having A+, a 3 in 8 chance of being O+, and a 1 in 8 chance for being A-.
An A+ parent and an O+ parent can definitely have an O- child
.
