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 refers to the transfer of genetic material (genes) between populations. It occurs when individuals migrate or move from one population to another and breed, thereby introducing new alleles (gene variants) into the recipient population.

• The first option describes the gene pool, not gene flow.
• The third option focuses on organism movement without emphasizing genetic transfer.
• The fourth option describes genetic drift, not gene flow.

Answer:

any movement of genes from one population to another
