Question

A person with blood group A produces antibodies against B. A person with blood group B produces antibodies against A. A person with blood group AB produces no antibodies. How can you explain this?

A and B alleles are co-dominant. Therefore, both A and B carbohydrates are present on the cell.

A is incompletely dominant over B. Both A and B carbohydrates are present on the cell.

A and B alleles are co-dominant. Half the cells have only A, and other half have only B.

Any ideas so far?

Answer 3

A :)))

Answer 4

Blood groups A and B are also codominated. Persons with homozygous A & B when marry produce children with AB group. The MN blood group aso exhibits codominance. dominance, dominant and recessive alleles lack typical dominant and recessive relationships. In the heterozygous conditions both the alleles of genes are capable of expressing themselves and therefore in the heterozygote, the traits occur side by side.

Answer 5

So, yes, you're correct! :D
