in the abo series, the gene for blood type o is while a and b are__ genes, and ab is
choices -dominant, codominant, recessive

In the ABO series, the gene for blood type O is recessive, while A and B are dominant genes, and AB is codominant.

Explanation:

A recessive allele can be described as an allele which gets masked by a dominant allele. Hence, a person having O blood type will have the genotype OO.

A dominant allele can be described as an allele which suppresses the effect of a recessive allele. Hence, a person with A blood type can have the genotype AA or AO. A person with blood type B can have the genotype BB or BO.

The blood group AB is co-dominant. The genotype of the person might be A, B, AB or O.

some inherited genetic mutations can be good for the offspring, so the answer is different genetic mutations cause many forms of cancer.
