Question

The primary result of natural selection is:

a. A species with larger body mass
b. To remove the strongest organisms from an ecosystem
c. To maintain a species' adaptation to its niche
d. To create fewer variations in a species

Answer 1

Natural selection acts on the population's heritable traits: selecting for beneficial alleles that allow for environmental adaptation, and thus increasing their frequency in the population, while selecting against deleterious alleles and thereby decreasing their frequency.

Step-by-step explanation:

Natural selection acts on the population's heritable traits: selecting for beneficial alleles that allow for environmental adaptation, and thus increasing their frequency in the population, while selecting against deleterious alleles and thereby decreasing their frequency. Scientists call this process adaptive evolution. Natural selection acts on entire organisms, not on an individual allele within the organism.
