What else can I help you with?
Can parents with blood group o positive and a positive have child with a positive blood group?
yes, for the blood types there are 2 genes that decide ABO/+- the ABO is based on a gene with 3 genotypes, which are i, IA and IB if a person has ii, they have O blood, if they have iIA or IAIA they have A blood, if they have iIB or IBIB they have B blood and if they have IAIB they have AB blood positibe/negative is the rhesusfactor, it actually works with 3 genes(C, D, and E), but anything other than cde/cde will give rhesus-positive blood, so a parent with ii-cde/cde will have O-negative, and iIA/CDe/CDe will give A-positive, the only 2 blood-types the children can have with this set of parents are A-positive and O-positive
If fathers blood group is O positive and mothers blood group is A negative can child blood group be A positive?
There is a 2 out of 4 chance that the child will be Rh +. The group could be 3 out of 4 that the child will be an A. So depending upon whether the fathers positive Rh is dominate gene.Yes there is a possiblity that a child from this couple would be A +.
Can child be A positive if both parents are O positive?
yes. even though me and my 4 brothers look alike only 2 of us share the same blood group and both our parents are a-
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 two a rh postivie parents have a 0 rh positive child?
The rhesus factor (positive or negative) of the child will be either positive or negative if one or both parents are positive, but the blood group can't be determined without knowing what both parents are. All humans inherit 2 blood alleles from their parents (one from each). Depending on the blood groups inherited, these will be made from either A,B or O. One of the 2 inherited alleles will become the dominant one, and therefore decide which blood group that person will end up being. It's possible for all blood groups (except "O") to have either 2 identical alleles or 2 different ones, but with the blood group "O", both alleles have to be "O". So both parents have to pass on the "O" allele to the child because blood group "O" can only occur if the allele is "OO". It's a little confusing, but put simply ......for your child to be "O" both parents need to pass on an "O" allele to the child. The rhesus factor is a whole different thing.
Is it rare for 3 of 5 kids to have o positive blood type and other 2 kids have a positive blood type with same parents?
No, it is not rare for 3 out of 5 kids to have O positive blood type while the other 2 have A positive blood type. Each parent passes on one blood type allele to their child, so it is possible for variations in blood type within siblings to occur based on the combination of alleles each child inherits.
What blood type would a baby have if mom and dad were a positive?
A/O, B/O, or O/O any combination. Each parent contributes one gene, A and B are dominant, so any combination that could result in O/O would result in a child with O blood. The Rh factor is similar. Rh positive is dominant, so the child would have to inherit 2 negative genes to be Rh negative. Each parent contributes 1 of the 2 he/she carries. Almost any blood type can result in a child with Rh + blood. +/+ or +/-. The child would have to inherit the - gene from BOTH parents (they would both have to be +/- or -/-) in order to be Rh negative. If both parents are Rh-, the child would be Rh-, otherwise it is hard to predict. Even if both parents are Rh+, it is possible for the child to be negative if both carry the recessive negative gene.
Can 2 negative blood types have a child with positive blood type?
Nope
Can a blood type b negative man father a blood type a positive child?
Yes, it is possible for a blood type B negative man to father a blood type A positive child. The ABO blood type system is inherited from both parents, with each parent passing on one of their two ABO genes to their child. This means that the child could inherit an A gene from the mother and a B gene from the father, resulting in a blood type of A positive.
Can 2 parents with type o have a child with a- blood?
the answer is no .. its just impossible
Can a parent with type a positive and a parent with type b positive have a child with o positive blood?
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.
Can a positive parents have o negative 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.)
