The intensity of selection acting on the couch potato gene--spatial-temporal variation in a diapause cline.

Evolution; international journal of organic evolution - 1 Feb 2014

Abstract excerpt

Cosmopolitan populations of Drosophila melanogaster have co-opted a form of reproductive diapause to overwinter in northern populations. Polymorphism in the couch potato gene has been implicated in genetic variation for this diapause trait. Using a collection of 20 populations from Florida to Canada and 11 collections from 3 years in a Pennsylvania orchard, we estimated the allele frequencies for 15 single...
