The migration of a mutant gene into isolated populations of Drosophila Melanogaster

Abstract

Sepia (eyed) D. melanogaster females were allowed to enter ‘bottle’ populations of wildtype D. melanogaster flies at rare, sporadic intervals. The frequency of sepia-eyed individuals in these populations was determined much more by selective forces than by numbers of immigrant individuals. Populations with no sepia individuals averaged nearly 3 immigrant individuals; those with more than 25% (homozygous) sepia flies averaged about 6 immigrants. After 34 generations, the average frequency of the sepia gene is about 0.28; this may represent the average frequency of any allele introduced into the wildtype populations by these migrant flies.
