Question

yesterday
gene flow changes allele frequencies in populations over time. which diagrams represent the process of gene flow?
select two correct answers.
diagram 1: two groups of butterflies, one group with mostly gray butterflies and one with mostly light gray butterflies, with an arrow from the light gray group to the gray group
diagram 2: a large circle with various shapes and smaller circles around it, with arrows indicating movement between them

Explanation:

Gene flow is the transfer of genetic material (alleles) between populations. The first diagram shows individuals (butterflies) moving from one population to another, which is gene flow. The second diagram shows a central population transferring genetic elements (symbols) to other populations, also representing gene flow. Other diagrams (not fully shown) likely don't depict this transfer.

Answer:

The two diagrams representing gene flow are:

1. The diagram with butterflies (one population of butterflies moving into another population).
2. The diagram with the central circle (containing different symbols) and arrows to/from smaller circles (transferring genetic elements between populations).
