Blood Types - Phenotypes and Genotypes

Question

Okay - so I know about the blood types, which ones are which, and I know how to fill out a Punnett Square - BUT:

I need to answer the questions in terms of phenotypes and I don't know how to turn Ao and Bo and such from a genotype to a phenotype. Help please!!

Answer 1

There are three different kinds of blood proteins; A, B, and O.

Here is the list of genotypes of blood types and their respective phenotypes.

AA - A blood type

AO - A blood type

AB - AB blood type

BB - B blood type

BO - B blood type

OO - O blood type

HTH. :]

Answer 2

there are A,B,AB and O types of blood groups . O is the universal donor and AB is the universal recipient.  

Answer 3

Blood types are an example of codominance.  O is recessive to both A and B, but A and B are codominant.

So:

AO and AA genotypes are A phenotype.

BO and BB are B.

OO is O.

AB is AB.

Answer 4

There are actually 3 kinds of blood groups namely A, B and O, disregarding the signs and other combined special groups.....

If the genotype of the blood is AO or OA from the parents, then A is dominant and O is recessive and thus the child would have A group.

If the genotype of the blood is OO from the parents, then the child would have O group.

If the genotype of the blood is BO or OB from the parents, then B is dominant and O is recessive and thus the child would have B group.

If the genotype of the blood is AB or BA from the parents, then the child would have A or B or AB group.

Hope that helped.........

Answer 5

I think the 1st questions been answered nicely by the ablove people

In answer to your 2nd question

"So, if Ao and Bo both show up in a Punnett square is there a possibility that the child's blood type will be O?"
