The wing type is controlled by an autosomal or non-sex-linked gene. The wild type (normal wing) trait is dominant, and the vestigial wing is recessive. But if you look at their eye color; red (wild type) versus white (mutant), that would be an example of a sex-linked trait.Niotulove Â· 8 years ago. Thumbs up.hose having no dominant (V) gene would have vestigial wings and would have a vv genotype. Flies with vestigial wings have nothing more than vestiges or degenerated elements of wings and are unable to fly. However, they can still jump and run quite well.
Lesson Summary. Though not common, sympatric speciation is an important evolutionary process that can separate a species into two new ones. This is a relatively uncommon form of speciation, though it has been observed in hawthorn flies and orcas.ympatric speciation occurs if interactions are so limited between these groups that mating no longer occurs between them. Each new population of flies will have genetic variation in its gene pool, which is the collective genetic information for the group.
