In humans blood type inheritance is an example of what?

Human blood type inheritance is an example of codominance, where both alleles for blood type (A and B) are expressed in the phenotype of individuals with the AB blood type.


Which blood type is characterized by codominance?

The blood type AB is characterized by codominance because both the A and B alleles are expressed equally on the surface of the red blood cells. This results in individuals with blood type AB having both A and B antigens present.


What are some examples of codominance in living organisms?

A red and white flower would be the result of codominance between the allele for red color and the allele for white color.A pink carnation is the result of incomplete dominance between the allele for red color and the allele for white color.


If a trait has three different phenotypes the trait is inherited by?

Typically, traits with three different phenotypes are inherited by a single gene with multiple alleles. In this case, each allele controls a different phenotype. Examples of traits with multiple alleles include human blood type (A, B, O) and eye color (blue, brown, green).


How is it possible to have neither allele dominant?

In cases where neither allele is dominant, both alleles are expressed equally in the phenotype. This is known as codominance, where both alleles contribute to the phenotype without one overpowering the other. An example of this is in blood type inheritance, where the AB blood type is the result of codominance between the A and B alleles.
