Question

which of the following best defines a gene pool?
the sum of all genetic traits in a populations 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:

To determine the best definition of a gene pool, we analyze each option:

• The first option: A gene pool is defined as the sum of all the genetic material (traits) present in the individuals of a population at a given time. This matches the scientific definition.
• The second option: Movement of genes between populations is gene flow, not a gene pool.
• The third option: Movement of organisms between environments is not related to the definition of a gene pool.
• The fourth option: Random change in allele frequency is genetic drift, not a gene pool.

Answer:

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