A gene showing codominance has:

One allele dominant on the other

alleles tightly linked on the same chromosome

alleles that are recessive to each other

both alleles independently expressed in the heterozygote

Solution

both alleles independently expressed in the heterozygote

A gene shows codominance when both alleles in heterozygous condition, express their traits independently instead of showing dominant-recessive relationship and such alleles are called codominant alleles.
