The following couple of questions discuss with the following description.

On the volcanic, equatorial West African island of Sao Tomé, two species of fruit fly exist. Drosophila yakuba inhabits the island's lowlands, and could also be found on the African mainland, located about 200 miles away. At upper elevations, and best on Sao Tomé, is found the very closely comparable Drosophila santomea. The two species can hybridize, regardless that male hybrids are sterile. A hybrid zone exists at center elevations, regardless that hybrids there are a great deal outnumbered via D. santomea. Studies of the two species' nuclear genomes reveal that D. yakuba on the island is extra intently associated with mainland D. yakuba than to D. santomea (2n = 4 in each species). Sao Tomé rose from the Atlantic Ocean about 14 million years in the past.

If the low selection of hybrid flies in the hybrid zone, relative to the collection of D. santomea flies there, is because of the incontrovertible fact that hybrids are poorly adapted to prerequisites in the hybrid zone, and if fewer hybrid flies are produced with the passage of time, those conditions will possibly lead toA. steadiness.B. reinforcement.C. fusion.D. additional speciation events.
