Complex epistasis for Dobzhansky-Muller hybrid incompatibility in solanum.
We examined the prevalence of interactions between pairs of short chromosomal regions from one species (Solanum habrochaites) co-introgressed into a heterospecific genetic background (Solanum lycopersicum). Of 105 double introgression line (DIL) families generated from a complete diallele combination of 15 chromosomal segments, 39 ( approximately 38%) showed evidence for complex epistasis in the form of genotypic and/or allelic marker transmission distortion in DIL F(2) populations.
