What is incomplete and codominance?

Answer 1

Codominant alleles will both be expressed in the phenotype. So for example in the human ABO blood type, A and B are codominant. This means that a person with the alleles AB will have the characteristics of both A and B (they will have both A and B antigens on their blood cells).

Another example of codominance - if B codes for black fur and b codes for white fur, an individual with Bb would have black and white spots/splotches/etc.

Incomplete dominance is different in that the phenotype is a mix of the two. So for example, if B codes for black fur and b codes for white fur an individual with Bb would have grey fur (a mix of black and white).

Answer 2

A dominant allele is a gene that holds a certain characteristic that is superior to a recessive allele. The dominant allele ALWAYS has its trait shown in the body of the recipient, except when both alleles in a gene are recessive.

Answer 3

An incomplete dominant trait is where neither allele for a trait is dominant nor recessive. An allele is, an alternative form of a gene (one member of a pair) that is located at a specific position on a specific chromosome.

Answer 4

Incomplete dominance is when both the dominant gene and recessive gene are present in an organism's phenotype. For example, since brown eyes are dominant and blue eyes are recessive in humans, a person who has incomplete dominance of eye color would have gray or green eyes; a mixture of both brown and blue.

Codominance is when two dominant alleles are present at the same time.

These two terms are not the same!

Answer 5

The word incomplete means that something is missing parts. Codominance is a relationship between 2 different versions of a gene.

Answer 6

It is called incomplete dominance.
