Question

many genes coding for one trait defines: epistasis incomplete dominance polygenic traits codominance rewatch

Explanation:

Epistasis is when one gene affects the expression of another. Incomplete dominance results in an intermediate phenotype between two homozygous phenotypes. Codominance is when both alleles in a heterozygote are fully expressed. Polygenic traits are traits controlled by multiple genes. Since the question refers to many genes coding for one trait, it is polygenic traits.

Answer:

C. polygenic traits
