Can two parents with type O blood have a child with type A blood?
Two O parents will get an O child nearly all of the time. But it is technically possible for two O-type parents to have a child with A or B blood, and maybe even AB (although this is really unlikely). In fact, a child can get almost any kind of blood type if you consider the effect of mutations.
Can an A+ parent have an O baby?
An A+ parent and an O+ parent can definitely have an O- child.
Why blood group O is most common in a population?
In order to be group O, you need both parent cells to be O. But group O is still more common simply because it is the ancestral form. The A and B mutations appeared in the last 20,000 years and haven’t spread through the population yet.
Can two O blood type parents have a baby?
O blood type. For example, two O blood type parents can produce a child with only O blood type. Two parents with A blood type can produce a child with either A or O blood types. Two parents with B blood type can produce a child with either B or O blood type.
What is the difference between Type O and Type O recessive?
The O allele’s recessive, meaning you can only have type O blood if your alleles are OO, whereas if you only have one allele that is an O, such as AO or BO, your blood type will be A or B respectively. The child will be blood type O, because as O is recessive then both parents will…
How does a person become Type O if they have children?
So, for a person to be type O both of their alleles have to match, and all of their children will get an O gene from them. If two people who are type O have children, all of the children will also be type O because those are the only alleles involved.
Can a child have both a and O genes?
If one parent contributes and A gene and the other contributes an O gene, the child will have A blood type, but, like his parents, he’ll also have both A and O genes that he may pass along to his children. However, in 1 out of 4 instances, both parents will contribute their recessive O gene to their child.
