Question

question 4 (mandatory) (2 points)
true or false? reproductive isolation is the end of gene flow between populations.
true
false
question 5 (mandatory) (2 points)
which type of reproductive isolation occurs when there are differences in the timing of reproduction that can prevent interbreeding?
ecological isolation
temporal isolation
behavioral isolation
mechanical isolation

Explanation:

For Question 4: Reproductive isolation means that populations can't interbreed, so gene flow stops.
For Question 5: Temporal isolation is about timing differences in reproduction (like different mating seasons) that prevent interbreeding. Ecological isolation is about different habitats, behavioral isolation is about different mating behaviors, and mechanical isolation is about physical incompatibility.

Answer:

Question 4: True
Question 5: Temporal isolation
