Summary

The dominantly inherited variant, red back, in the migratory grasshopper,Melanoplus sanguinipes, is rare in nature. The present study illustrates that is this probably due, in part, to the trait's association (either through pleiotropy of the red back gene,Pro and/or closely linked fitness loci) with lower egg hatchability, greater developmental time, greater mortality during later stages, and a greater tendency to have an extra instar.

Key words
