Genetics of the photoperiodic diapause in Drosophila littoralis [strains from Finland and Switzerland]

The reproductive diapause of Drosophila littoralis is terminated by long daylength and sufficiently high temperature. The genetic basis of this phenomenon has been investigated by crossing dia‐pausing and non‐diapausing strains with each other. The results suggest that the genetic control of reprodu...

Description
Summary:The reproductive diapause of Drosophila littoralis is terminated by long daylength and sufficiently high temperature. The genetic basis of this phenomenon has been investigated by crossing dia‐pausing and non‐diapausing strains with each other. The results suggest that the genetic control of reproductive diapause can be explained on the basis of one major locus with multiple alleles or a cluster of linked loci. Diapausing appears to be dominant over non‐diapausing.
