Question

genetic changes in populations that are brought about by horizontal gene transfer in bacteria are an example of which means of evolution? gene flow the founder effect natural selection genetic drift

Explanation:

Gene flow is the transfer of genetic material between populations. Horizontal gene transfer in bacteria (transferring genes between different bacteria, not parent - offspring) is a form of gene flow. The founder effect and genetic drift are about random changes in small populations, and natural selection is about differential survival/reproduction based on traits. So the correct option is gene flow.

Answer:

gene flow
