Art [367]

Answer;

all individual variation is due only to environmental factors

A population of organisms will not evolve if all individual variation is due only to environmental factors.

Explanation;

-Evolution of organisms is influenced by several factors which include; natural selection, random genetic drift, mutation, and gene flow.

-Mutation is a random heritable change in a gene or chromosome, resulting from additions, deletions, or substitutions of nitrogen bases in the DNA sequence. Gene flow works to decrease the variation between the two populations.

-Genetic drift is the random change in allele frequency from one generation to the next.. Natural selection is the process by which some organisms have a greater chance of surviving and reproducing than others due to features that are better adapted to the environment.
