Yes this is true only if both parents are heterozygous positive. This means that the parents genotypes are +- for blood type. + blood type is dominant over - blood type, so this means that one can only have negative blood type if their parents are either heterozygous or homozygous recessive.
A helpful tool to finding out the probability for this question would be to use a punnett square. If you used this method you would find out that two heterozygous positive blood type parents have a 25% chance of producing offspring with negative blood type.
What else can I help you with?
Can a a positive father and a o negative mother produce a a negative child?
Yes, if both the mother and the father are carriers of the recessive Rh negative trait, they can produce a child with O negative blood type. The child would inherit one Rh negative allele from each parent, resulting in a negative blood type.
Can ah O negative and a O negative have a baby with O positive?
No. Two negatives can't make a positive.
What blood GROUP do parents have to have a child with type o negative blood group?
For two parents to have a child with type O negative blood group, both parents must have at least one O and one negative Rh factor allele. The possible parental blood group combinations could be O negative x O negative, O negative x O positive, A negative x O negative, or B negative x O negative.
What blood type does a 0 negative and a b positive make?
The possibilities include B positive, B negative, O positive, O negative.
Can two parents with b positive make o positive?
Yes. The child will be either A positive or B positive or even AB positive. If the grandparents have a negative (A negative, B negative), there is a slight chance that the child will have a negative. A type O is out of the question. The fact that there are two positive parents means that there is no risk to the mother of Rh negative disorders.
Can two o positives blood groups make a a positive blood group?
A and B
Can a a positive father and a o negative mother produce a a negative child?
Yes, if both the mother and the father are carriers of the recessive Rh negative trait, they can produce a child with O negative blood type. The child would inherit one Rh negative allele from each parent, resulting in a negative blood type.
Can ah O negative and a O negative have a baby with O positive?
No. Two negatives can't make a positive.
Can 2 o positives have an A positive or negative baby?
Yes, it is possible for two O positive individuals to have a child with A positive or A negative blood type. This is because each parent can pass on either an A or an O allele to their child, leading to a variety of blood type combinations in offspring.
Can two parents with A negative blood type make a O negative baby?
Yes
What combination of blood makes you b positive?
two o positives
Can parents both blood type B positives have a child with O positive blood type?
Yes, two B positives can produce an O positive child.
Can O positive and O negative make B negative?
Yes
Can B negative and O positive make O negative?
Yes
What type blood does O negative and A positive make?
they can have a A positive A negative O positive O negative depending on genes of A
Is rh negative blood compatible with o positive?
can two o positive blood types make an RH Negitive baby
Can an o negative mother and an o positive male make an o positive child?
yes I have o negative my husband has o positive; I have daughter with o negative and a son with o positive
