yes. because of recessive genes. recesive genes are traits that will not be shown if the dominant gene for that trait is present. every person has at least two alleles(forms of traits) for each trait that is shown. One you see and the other you may not. For example, two parents may have brown eyes, but if they have a child that has blue eyes then you know that the parents must have carried the recessive gene. this is possible because the brown eye allele is dominant and the blue eye allele is recessive. Even though you did not see the blue eye trait in either of the parents it was still present.
What else can I help you with?
Can a b positive and a positive have a b negative child?
No. If both parents are positive, the child will be positive. If both parents are negative, the child will be negative. Parents who are negative and positive can have children who are either positive or negative. '+' + '+' = '+' '-' + '-' = '-' '+' + '-' = '-' or '+'
Can parents that are both a negative have an ab positive child?
No. If both parents are A negative the child can only be A negative or O negative. If the child is AB positive at least one parent must have type B or AB blood and at least one must be RH positive.
Can an o negative child have both parents which are 0 positive?
No, an O negative child cannot have both parents with O positive blood types. While both parents can pass on an O allele, they would each contribute a Rh positive factor, resulting in a child with a positive Rh factor. For a child to be O negative, they must inherit the Rh negative factor from both parents.
If both parents are A positive what usually will the child have?
A or O positive or negative
If both parents of a child is posititive can the child be negative?
yes because you either get your parent's traits, the opposite traits, or a little of both but because both parents are positive the child could be positive OR negative
Can O negative parents have an O positive child?
If they are both O negative, no, the child will be O negative.
Can 2 Rh parents have a Rh- child?
No, it can't happen. if one of the parents or both are +, the child will be Positive. I don't know if 2 negatives can have a positive. But i do know that if one of the parents is positive and the other is negative, you can have a either a positive or negative child. (I have twins, one is negative and the other is positive.)
Can o positive and a positive parents have o negative child?
Yes. Since the Rh factor is recessive if both parents have a copy of the gene they can have an Rh negative child.
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 a child have a negative blood types if the parents are both a positive?
Yes! Parents have two genes for pos/neg blood type, and only one of them needs to be positive for the parent to have positive blood type. Most positive-blooded people have one positive gene and one negative gene. If both positive parents pass on their negative gene, they can have a child with a negative blood type.
Can 2 A positive parents have an O negative child?
No. O and Rh negative are both recessive traits--both alleles must be that trait before it expresses. The term for an A positive child from two O negative parents is "grounds for divorce."
If both parents are A positive can a child have negative blood?
Yes. If both parents have the recessive gene for Rh negative, a child of theirs could have Rh negative blood. I have two daughters who are Aneg, and both of us are A+.
