The answer is yes, the parents have to be heterozygous in this case. which means (B,b). The B is the dominant trait, so it masks the recessive one (b).
In other words, B is the b+ genotype while the b is the o+ blood type.
If you draw a punnet square label the top and side with the heterozygous term. (B.b)
4 outcomes are possible (remember other factors will change the outcome.)
(B,B) (B,b) (B,b) (b,b)
The (b,b) offspring is recessive and has the O+ blood type
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.
If they both have type A blood, they cannot have a child type B.
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.
Yes, you very much can have a child with O positive blood.
yes it can be possible too as the parents is already with an o blood group..
Yes. They can have B+, B-, O+, and O-.
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.
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.
A & B + respectively
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.
No, they will have a O negative child.
You could have several children with different blood types. you get your blood type from either parents or even grand parents.
