Question

natural selection can make variations that are advantageous, or helpful, more common in a population over many generations. but not all advantageous variations are affected by natural selection. natural selection affects only variations that are inherited, or passed down from parents to offspring through genes. genes are pieces of hereditary material containing instructions that affect inherited traits. natural selection does not affect variations that are acquired, or gained during an individuals life. acquired variations can be learned by an individual or caused by the environment, but they cannot be passed down through genes. which of the following describe a mouse with a variation that could be affected by natural selection? select all that apply. a mouse that develops a strong body from running a lot a mouse that inherited a strong sense of smell from its parents a mouse with black fur that was passed down through a gene a mouse that has a scar on its back after being injured

Explanation:

Natural selection affects inherited variations passed down through genes. A mouse with a strong sense of smell inherited from parents and black fur passed down through a gene are inherited traits. A strong body from running and a scar are acquired, not inherited.

Answer:

B. a mouse that inherited a strong sense of smell from its parents
C. a mouse with black fur that was passed down through a gene
