Question

What can the researcher conclude about Sunshine periwinkle and Summer periwinkle?

1) These plants are not a good example of separate species.
2) These plants are temporally reproductively isolated from each other.
3) The fact that Summer periwinkle blooming time can be manipulated suggests it should not be regarded as a species distinct from Sunshine periwinkle.
4) These plants are genetically incompatible.
5) These plants are not pre-zygotically isolated from one another.

Answer 1

The researcher can conclude that Sunshine periwinkle and Summer periwinkle are not pre-zygotically isolated from each other.

Step-by-step explanation:

The researcher can conclude that Sunshine periwinkle and Summer periwinkle are not pre-zygotically isolated from each other. This is because the fact that Summer periwinkle's blooming time can be manipulated suggests it should not be regarded as a species distinct from Sunshine periwinkle. Therefore, option 5) These plants are not pre-zygotically isolated from one another is the most appropriate conclusion.
