Which of the following best defines a gene pool?

A. The sum of all genetic traits in a population's individuals at a given time.
B. Any movement of genes from one population to another.
C. Any movement of organisms from one environment to another.
D. The random change in the frequency of an allele in a population.

Gene pool is the entire collection of genetic material in a population or species, encompassing all the alleles and their frequencies. It represents the genetic diversity within a population and serves as the raw material for evolution through natural selection.

Genetic variation in the gene pool is crucial for a population's adaptability to environmental changes and for the survival of advantageous traits. Allele frequencies in the gene pool determine the genetic makeup of a population and influence evolutionary processes over time.

Gene flow and genetic drift are factors that can impact the gene pool by introducing new alleles or causing changes in allele frequencies, respectively, shaping the genetic composition of populations.
