Question

The original habitat of the North American maggot fly, Rhagoletis pomonella, was native hawthorn trees. About 200 years ago, some populations colonized newly introduced apple trees. The two populations are still classified as subspecies, but sympatric speciation is underway. What has contributed to incipient speciation in the maggot fly?

Answer 1

Answer:

A. Because apples mature more quickly than hawthorn fruit, the apple-feeding flies have been selected for more rapid development

Explanation:

• The North American maggot fly is a native to the eastern North America and is breeds on the large fruits of the large hawthorn trees and tip of the females in more narrowly and pointed than the males and the rapid development of the trees these fly have incipient specialization and adaption towards the apple trees and their scents have more attraction to them.
