Can 2 O+ people have an O child?
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.
What blood type if parents are both O?
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.
Can siblings have different O blood types?
If the child has two Os, the child has Type O blood. So depending on which genes the parents have, siblings can easily have different blood types.
What blood types make O positive child?
Each biological parent donates one of their two ABO alleles to their child. A mother who is blood type O can only pass an O allele to her son or daughter….How are ABO alleles inherited by our children?
| Inherited | Blood type of child |
|---|---|
| O from the mother A from the father | A |
| O from the mother B from the father | B |
Can two A parents have an O baby?
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.
Can 2 O positive parents have an A negative child?
So, is it possible for two people who are Rh-positive to produce a child that’s Rh-negative? The answer is yes — but only if neither parent passes along Rhesus D.
Can two O positive parents have O negative child?
A. Before I delve into the science, let me quickly stop any tongues that might be wagging if you are asking about a paternity debate: Yes, two O-positive parents could have any number of O-negative children. In fact, according to the experts, most children who are O-negative have parents who are O-positive.
What cross would produce a child with type O blood?
Question 3. Remember, because type O blood results from the homozygous recessive genotype (i i ), the only way to produce a type O child is if both parents provide an O allele (i ). Since the father has blood type A, he must be heterozygous (IA i ).
