Which of the following can be factors in both sympatric and allopatric speciation? a. habitat differentiation.
b. geographic separation stion.
c. gene flow.
d. sexual selection.
e. polyploidy.

Option B.

Geographic separation.

Explanation:

It is geographic separation that is common to both of them because

Sympatric speciation to occur when certain populations of species isolate reproductively from the the main populations because they can not longer interbreed with each other and they inhabit the same geographical location.

Allopatric speciation occur when two populations of the same species separate from each other geographically which can be as a result of one group of population move to another geographical location.

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.

the correct answer is:

a population changes in response to a change in the environment.
