Question

the majority of human traits are polygenic, which means they are __________. a. determined by a single gene b. developed at birth c. influenced by multiple genes d. learned over time please select the best answer from the choices provided

Explanation:

The term 'polygenic' is derived from 'poly -' meaning many and '-genic' related to genes. So, polygenic traits are influenced by multiple genes. Option A is for monogenic traits (single - gene). Option B is incorrect as polygenic traits can develop over time and not just at birth. Option D is about learned traits, not related to the genetic basis of polygenic.

Answer:

C. influenced by multiple genes
