Question

1. how do codominance and incomplete dominance affect a population?

Explanation:

Codominance shows both alleles' phenotypes simultaneously, increasing phenotypic diversity. Incomplete dominance creates intermediate phenotypes, also contributing to a wider range of observable traits in a population. These can affect natural selection pressures and genetic structure over time.

Answer:

Codominance and incomplete dominance increase phenotypic diversity in a population, which can influence natural - selection and genetic structure.
