Question

H) Which of the following factors is most likely to contribute to reproductive isolation? (1 point)
A sudden change in climate
Physical barriers separating populations
Increased competition for food resources
Random fluctuations in allele frequencies

Answer 1

Physical barriers separating populations are most likely to contribute to reproductive isolation. When populations are separated by physical barriers, such as mountains or rivers, they can evolve independently, leading to differences that prevent them from interbreeding, even if they come into contact later.
