Question

Which of the following best defines a gene pool?

O the sum of all genetic traits in a population's individuals at a given time
O any movement of genes from one population to another
any movement of organisms from one environment to another
O the random change in the frequency of an allele in a population

Answer 1

"A gene pool" is best defined as "the sum of all genetic traits in a population's individuals at a given time."

A gene pool is the total collection of genes and their variants (alleles) that exist within a population of a particular species. It includes all the genetic information that is passed from one generation to the next through reproduction. The gene pool of a population can change over time due to various factors such as mutation, genetic drift, gene flow, and natural selection.
