Question

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

Explanation:

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

• The first option: "any movement of genes from one population to another" matches the scientific definition of gene flow, which involves the transfer of genetic material (genes) between populations.
• The second option refers to movement of organisms (not genes), which is different from gene flow.
• The third option describes the gene pool (sum of all genetic traits in a population), not gene flow.
• The fourth option defines genetic drift (random change in allele frequency), not gene flow.

Answer:

A. any movement of genes from one population to another
