If a trait has no basis in reproductive cells why will its importance in evolution be low?
Answer and explanation
Correct answer: Because it cannot pass generation to generation
The governing concept is inheritance across generations. Reproductive cells carry genetic information to offspring, allowing a heritable variation to be transmitted and possibly become more or less common through selection or other evolutionary processes. A trait that exists only in body cells, such as many acquired changes, normally cannot be passed through reproduction, so it contributes little directly to evolutionary change. Therefore A is correct; dominance, fossils, and chromosome-number increase do not explain transmission.
