Solution

The correct option is A 1:2:1
Codominance is the condition in which products of both alleles are expressed in the phenotype of the heterozygote, side-by-side. Both the alleles are equally dominant and thus in a heterozygous condition both the product of the allele are detectable.
Take the example of coat color in short horned cattle which shows codominance. $F_{1}$ cattle coat color is roan; upon crossing the $F_{1}$ , red, roan, and white coat color cattle are produced in the ratio of 1:2:1 in the $F_{2}$ generation.

Select the incorrect statement(s).

I. Multiple alleles are the product of repeated mutations of the same gene, but in different directions.

II. In codominance, both the alleles of the gene express themselves independently as both are dominant.

III. Incomplete dominance results in two different phenotypes in the hybrid.
