Question

Which idea is depicted by a cross in which the F₁ generation resembles both the parents?

Options

• Inheritance of one gene

• Codominance

• Incomplete dominance

• Complete dominance

Answer 1

Codominance

Explanation:

When both alleles are present in codominance, they are able to express themselves independently, resulting in a phenotype that is intermediate between both parental homozygous phenotypes, resembling both, for example, roan coat colour in cattle is a result of codominance of alleles for white and red coat colour.
