Question

Which type of selection can lead to the formation of new species if gene flow is restricted?

पर्याय

• Disruptive selection

• Artificial selection

• Stabilising selection

• Directional selection

Answer 1

Disruptive selection splits the population into two distinct phenotypic groups. If gene flow between these groups is restricted, each sub-population may ultimately evolve into a new species, giving disruptive selection direct speciation significance.
