Question

which of the following best defines a gene pool?
the sum of all genetic traits in a population’s individuals at a given time
any movement of genes from one population to another
any movement of organisms from one environment to another
the random change in the frequency of an allele in a population

Explanation:

• The movement of genes between populations is gene flow, not a gene pool.
• Movement of organisms between environments is migration, unrelated to the gene pool definition.
• Random change in allele frequency is genetic drift, not a gene pool.
• A gene pool specifically refers to all the genetic material (traits/alleles) present in a population at a specific time.

Answer:

the sum of all genetic traits in a population's individuals at a given time
