Question

What type of pattern of inheritance is represented by the genetics of human blood types? Select the 2 answers that apply.

The human blood type gene is an example of a gene with multiple alleles: A, B, 1.
A and show codominance because both alleles are equally expressed in blood type AB.
OA and B show incomplete dominance because both alleles are partially expressed in blood type A and B.
The human blood types are an example of polygenic traits with four possible phenotypes: A, B, AB, O.

Answer 1

The human blood types are an example of a gene with multiple alleles and codominance because both the A and B alleles are equally expressed in blood type AB. They are also an example of a trait with discrete, non-continuous phenotypes, as there are four possible blood types: A, B, AB, and O. Therefore, the correct answers are:The human blood type gene is an example of a gene with multiple alleles and codominance because both alleles are equally expressed in blood type AB.The human blood types are an example of a trait with discrete, non-continuous phenotypes, as there are four possible blood types: A, B, AB, and O.
