Question

Complete the T-chart by categorizing each statement as something that would most likely be relevant to gene flow or genetic drift. Some answers will fit in both columns depending on the situation.


is random

is a mechanism for evolution

is often related to disasters

is also called “migration”

deals with movement between populations
A 2-column table has columns with labels gene flow and genetic drift.

Answer 1

Gene flow
- is also called “migration”
- deals with movement between populations
- is a mechanism for evolution (also fits drift in general)

Genetic drift
- is random
- is often related to disasters (bottlenecks/founder effects)
- is a mechanism for evolution (also fits gene flow)

Note: "is a mechanism for evolution" applies to both. "Is random" primarily describes genetic drift; gene flow can be random in some cases but is usually directional (movement-driven).
