Can 2 parents with blood type A have a child with blood type O?

Even though both parents still have blood type A, Dad can pass on either his A or his O gene version. Mom can also either pass on her A or her O. Because of this, you can see that there’s 1 in 4 or 25\% chance for a child to have OO, or blood type O. How did I get a 1 in 4 chance?

Can 2 A+ blood types have an O 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.

What is the probability of a child being a daughter with blood group O if the parents are both heterozygotes with blood group A?

If the father is heterozygous, there is a 50\% probability for a blood type A child and a 50\% probability for a blood type O child.

What is the probability of a girl child with blood group O when the parent have blood group A and B?

The probability of having a girl child with blood group O when the parents have blood group A and B is. A. 0\%

Do children have same blood type as parents?

Yes, a child is able to have a different blood type than both parents. Which parent decides the blood type of the child? The child’s blood type is decided by both parents’ blood type. Parents all pass along one of their 2 alleles to make up their child’s blood type.

How is blood type determined from parents?

Blood Inheritance 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 is the possibility of having a child with O blood?

If mom passes her O and so does dad, then the child will be OO which is O type blood. Each parent has a 50\% chance of passing down the O gene. So each child has a 25\% chance of ending up with an O blood type.

What are the possible blood groups of a child whose parents have blood groups A and 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.

What happens if both parents are O positive?

A child with type O blood can have parents with type A, type B, or type O blood, but not type AB. Conversely, if two parents both have type O blood, all their children will have type O blood.

What is the blood type of a child of two parents?

Each parent gives one of their two ABO alleles to the child (3). Mother with AB blood type can either pass the A or B allele to the baby. Likewise, a father with O blood type can only pass O allele to the baby. If both parents belong to the blood group O, the child will also belong to the O blood group.

How do you calculate the probability of having a different blood type?

For example, your blood group is A, and your partner’s is AB, you can calculate the probabilities for possible blood types as follows: Write down your blood type and accompanying alleles. As your blood group is A, you either have AA or A0 alleles. Your child will either inherit an A allele (75\% chance) or 0 allele (25\% chance).

How do you determine the genotype of a child with O blood?

If the father has blood group A and mother blood group B, work out the genotypes of the parents and the possible genotypes of the other offsprings. To have a child with O blood group, both paretns should have atleast one copy of i allele.

Can two people with B blood type have a baby?

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