Question 6
H

Two populations of one plant species are separated by a mountain range. Occasionally, insects carry pollen from one population to the other population. What is the effect of this pollen transfer on speciation?

[1]
A

Speciation is faster, because new mutations are introduced into each population

B

Speciation is faster, because the two populations become more different from each other

C

Speciation is unaffected, because the two populations are still geographically apart

D

Speciation is slower, because alleles are shared between the two populations
