Question

complete the sentence using one of the following words: polygenic, codominance, or incomplete dominance. human adult height and skin color are examples of traits.

Explanation:

Polygenic traits are influenced by multiple genes. Human adult height and skin color are determined by the combined effects of several genes. Codominance involves both alleles being expressed equally (e.g., AB blood type). Incomplete dominance shows a blended phenotype (e.g., pink flowers from red and white parents). Since height and skin color are due to multiple genes, the correct term is polygenic.

Answer:

polygenic
