With genetic mutations during replication, anything is possible.
But, in general two O negative parents could only have a child that is O negative. Conversely, two O positive parents could have a child that is either O negative or O positive.
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.)
Depending on their genotype this can be possible. A, B and O refer to the so-called phenotype, which means the actual testable result of genetic information. The genotype on the other hand refers to the actual genetic information of an individual. There are basically three genes that code the AB0 system, a gene for A, a gene for B and a gene for 0 (actually there are subtypes, but this is not important here). Everyone has two genes, one on each chromosome of a pair of chromosomes. One gene is inherited form the mother, the other one from the father. This combination is called genotype. Depending on the combination of genes the four phenotypes are formed. The genotypes are AA and A0 for phenotype A, BB and B0 for phenotype B, AB for phenotype AB and 00 for phenotype 0. Now to answer the question precisely one would have to know the genotypes of the parents. For example if the parents are genotypes A0 and B0 then the children could have any of the four blood types. The answer would be "yes", as it is possible for the child to to inherit the gene (better a gene) for the positive rhesus factor if both parents have it. If on the other hand the parents have the genotypes A0/BB, AA/B0 or AA/BB then it is impossible for them to have a child with blood type 0 as no combination would produce the genotype 00 necessary for the phenotype 0. Conclusion: It it can be possible. So a child with blood type 0 positive can come from a couple with blood types A positive and B positive. But not all couples with this constellation of blood types will be able to have a child with blood type 0.
If both parents are type O, they will always produce type O offspring.
No they cannot. They can only have a child with type A or type O blood.
Yes, it is possible for a mother with AB blood and a father with O blood to have a child with O blood type. This is because the parents can each pass on an O allele, resulting in a child with O blood type.
Yes, the child of these parents could have either blood type O+, O-, A+, or A-.
Assuming both parents are O positive (OO), they can only pass on the O allele. However, since one child is A positive, it means that one parent has the A allele (AO). This scenario is not possible with two O positive parents genetically. Therefore, the chance of both O positive parents having three O positive children and one A positive child is not genetically feasible.
No.
Yes, the child of these parents could have either blood type O+, O-, A+, or A-.
Yes, we all get our blood groups from either our parents and even grandparents.
Yes, parents with blood group O positive can have a child with blood group O negative. This is possible if one parent is heterozygous for the Rh factor (one parent has both positive and negative Rh alleles), allowing for the possibility of the child inheriting the negative Rh factor.
Yes they can.
yes, like if both parents are blond, child may have black hair
No, they can't. But they can have kids with type 0.
Yes
Can parents with both negative blood have a child and how much of a chance for that child having a dissabillity
Yes, it is possible for an A positive blood type man and a B positive blood type woman to have an O positive child. The child would inherit one A allele from the father and one B allele from the mother, resulting in the child having an O blood type.
