Question

a biology teacher asks students to give examples of genetic variations that support the idea that changes in a populations environment affect genetic variation. which is the least supportive example?
changes in genetics in human populations
antibiotic resistance in bacteria populations
pesticide resistance in garden insects
changes in the color of the peppered moth population in england

Explanation:

Antibiotic resistance in bacteria, pesticide resistance in insects, and peppered moth color changes are classic examples of environmental pressures (antibiotics, pesticides, industrial pollution) driving genetic variation and natural selection. In contrast, "changes in genetics in human populations" is too vague and does not explicitly link to a specific environmental factor causing the genetic variation, making it the least supportive example.

Answer:

changes in genetics in human populations
