Question

Can the percentage of individuals with certain traits in a population change because the environment changes?

a. No, the percentage of individuals with certain inherited traits in a population changes randomly from one generation to the next, never as a result of changes to the environment.
b. Yes, when the environment changes, individuals with certain inherited traits survive and reproduce and other individuals with different inherited traits die, and this changes the percentage of individuals with certain traits in a population.
c. No, the percentage of individuals with certain inherited traits in a population cannot change because a population is all one species and so will always have the same inherited traits.
d. Yes, when the environment changes, individuals in a population can change their inherited traits to better fit the environment, and this changes the percentage of individuals with certain traits in that population.

Answer 1

Yes, when the environment changes, individuals with certain inherited traits survive and reproduce and other individuals with different inherited traits die, and this changes the percentage of individuals with certain traits in a population. Option B is correct

Natural selection is the name given to this process. Through this process, animals that are more suited to their surroundings have a higher chance of surviving, procreating, and transferring their beneficial features to their progeny.

This may eventually cause a shift in the proportion of people in a population who possess particular features.

Therefore, Option B is correct.
