2, AA, and AO
The baby's blood group depends on the genotypes of both parents, not just one.
Use a punnet square it may be a little tricky though.Just remember which letter is dominant and which one is recessive.heterozygous and Homozygous.
Although there are actually several genes which determine ABO-type, they are usually placed into the three basic groups i.e. A, B and O.For each phenotype, the genotypes follow:O: OO is the only possibility.A: AA or AO are both acceptable.B: BB or BO are both acceptable.AB: AB is the only possibility.
Many possible genotypes, producing ,any possible phenotypes.
People receive a total of 46 genotypes from their parents.
A rare blood type is a blood type that can be used for blood transfusions in many patients. The rarest blood type is O negative; or the blood type of a universal donor. If you have a rare blood type, you can find out by getting checked out by a doctor or looking through your genetic history.
It really does depend on the population in the U.S. but it has been stated that the rarest blood type is AB-. This is according to the American Red Cross
There are three alleles for blood type: IA=Blood type A IB=Blood type B i=Blood type O The alleles for blood type A and B are codominant so when someone contains the IA and IB alleles, their blood type is AB.
There is only one normal type of red blood cell.
they are 21C2 combinations
The combinations are endless!
No. Often a child can have a completely different blood type from their parents or even the same. It really depends on their genetics.Some combinations of parents are unable to get children with certain blood types - assuming no mutations occur.Regarding the AB0-system:If both parents have blood type 0, all their children will have blood type 0.If both parents have blood type A, no children will have blood type B or AB.If both parents have blood type B, no children will have blood type A or AB.If both parents have blood type AB, no children will have blood type 0.Of course you can be more specific if you know the parents' genes.
