Question

When both alleles are expressed in the phenotype of heterozygotes, the type of inheritance is:codominance.incomplete dominance.multiple alleles.X-linked.

Answer 1

In this case, we need to look carefully, from the available options, there are two that could apply, one is codominance and the second is incomplete dominance, in the second case we have that both alleles express nonetheless they form an intermediate phenotype, meanwhile, in the first case both alleles are expressed equally, forming in many cases a spotted or specked pattern, therefore the correct answer is codominance.
