Question

which of the following best defines gene flow? 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:

Gene flow is defined as the transfer of genetic material (genes) from one population to another. This can occur through processes like migration of organisms that carry their genes with them.

• The first option describes the gene pool (sum of all genetic traits in a population at a given time), not gene flow.
• The third option is about movement of organisms (which can cause gene flow if they reproduce in the new area and transfer genes, but the key is the movement of genes, not just organisms).
• The fourth option describes genetic drift (random change in allele frequency), not gene flow.

Answer:

any movement of genes from one population to another
