A person's blood type in the ABO system denotes the presence or absence of the A and B antigens. The antigens are molecules on the surface of the red blood cells;
Group A people have the A antigen
Group B people have the B antigen
Group AB people have both A and B antigens
Group O people do not have A or B
Each person has two genes controlling their ABO blood type; one they inherit from their mother, and one from their father. The A and B genes, if present, will always be expressed, so it is possible to have an A gene and an O gene, but the blood type will be A.
If a person is group O, then they have two O genes. If two people who are group O have a baby together, the baby will only inherit the O gene from each parent and will therefore be group O.
What else can I help you with?
Can parents with b negative blood have a child with o positive blood?
If both parents are B- they can only have children who are B- and O-. One would have to be positive in order to have a child with positive blood.
Can parents with a positive blood have b positive child?
If they both have type A blood, they cannot have a child type B.
Can O positive blood group and B positive blood group parents have child?
Yes, it is possible for parents with O positive and B positive blood groups to have a child with either O positive or B positive blood group, as each parent can pass on either their O or B allele to their offspring.
Can parents with b positive and a negative blood have a child with o positive blood?
Yes, you very much can have a child with O positive blood.
Can parents with b positive and o positive blood have a child with b negative blood?
yes it can be possible too as the parents is already with an o blood group..
Can parents who have B negative and O positive blood types have a child with B positive blood?
Yes. They can have B+, B-, O+, and O-.
Can parents both blood type b positive have a child with blood type ab positive?
Yes, it is possible for two parents with blood type B positive to have a child with blood type AB positive. This is because the child can inherit one B allele from each parent to make blood type AB.
Can o positive and o positive have b positive baby?
No, two parents with O type blood cannot have a child with B type blood. This is because O is recessive - meaning in order to have type O blood, you need to have two O alleles. Therefore if both parents have O blood, all their children have to have O type blood. In order to have a child with B type blood, at least one parent needs to have B or AB type blood - in order to donate the B allele to the child.
What type blood do parents have to have for their child to have ab positive blood?
A & B + respectively
Can parents b positive and O positive have a b negative child?
Yes, it is possible for parents with blood types B positive and O positive to have a child with blood type B negative. This can occur if the parents are both carriers of the negative Rh factor and pass it on to the child.
Can parents who have B negative and O positive blood types have a child with O positive blood?
No, they will have a O negative child.
How can a child's blood type be b positive if mom is b positive and dad is a positive?
You could have several children with different blood types. you get your blood type from either parents or even grand parents.
