Which statement best describes codominance and incomplete dominance?

This question lacks options, the options are;

A) In codominance and incomplete dominance, both of the alleles are dominant.

B) In codominance and incomplete dominance, neither of the alleles are dominant.

C) In codominance, both of the alleles are dominant; in incomplete dominance, neither of the alleles is dominant.

D) In codominance, neither of the alleles is dominant; in incomplete dominance, both of the alleles are dominant.

The answer is C

Explanation:

Codominance and incomplete dominance are both a type of non-mendelian inheritance pattern i.e. patterns of inheritance that do not follow mendelian principles.

- In codominance, the alleles of a gene are both dominant and hence, both express themselves simultaneously for that trait. An example is the alleles A and B of the blood group in humans where both A and B are dominant in the gene.

- In incomplete dominance, neither of the two alleles of gene is dominant and none is recessive either. This means that the two alleles blend together to form an intermediate phenotype in a heterozygous offspring. An example is the pink flower in four o'clock plants resulting from the blending of red and white alleles.
