O blood is the most common
In human blood there are three different alleles (A, B O). Every person has two of these, and passes on ONE to their biological offspring -- one from mother and one from father. A and B alleles are dominant, which means that, if present, they will always show up. O is recessive, which means that it will only show up if there is no dominant allele present. Alleles passed from Parent1+Parent2 form blood types as follows: A+A = Blood Type A A+O = Blood Type A A+B = Blood Type AB B+B = Blood Type B B+O = Blood Type B O+O = Blood Type O Since the O allele is recessive, for a baby to have O type blood, both parents must also be O type.
If BOTH the parents have Type O blood, then their child has a 100% chance of having Type O blood. If ONE of the parents has Type O blood, then it has a lower chance. For more information, look up "Punnett Squares"
Yes, if both the father and mother have the genotype of AO, then they would both show up as phenotype A and they could have a child with type O blood. As O is recessive, the type A would be dominant and therefore show up as the blood type. The mother could contribute the positive Rh factor leading to type O+ in the child.
O positive is the most common blood type making up about 38% of the population.
Yes, because if anyone related to the parents ever had ab type blood then that triat could show up in the baby.
Yes.
O positive blood is more common among Americans. It is one of the most commonly stored blood types in blood banks today. I am not sure of the numbers but I know that a lot of people say they are O positive.
All four of the basic blood types can be either be positive or negative, they are A,B,AB, and O. Blood types are used to used define each person blood, they help to make blood transfusions more successful by matching up the blood types.
It does not matter what your blood type is or what your husband's blood type is. It's more important for blood types for transfusion.
People with O+ blood can receive either O+ or 0- blood, but an organ match requires more than just the right blood type.
The father would be 'o' because 'o' is recessive. That means that its a weaker gene, so other genes are more dominate. So if there was another gene the baby would be that blood type not 'o'. For more help Google 'Punnet Squares'
Anyone can donate blood.The tricky part is deciding which person can receive your blood - it's based on blood types. Type O, for example, can only receive more type O and you also have to match up the Rh factor for + or - (+ can receive anything, - can only take more - blood). Type AB can receive any blood so long as the Rh factor matches up properly.
