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.
我们研究了来自一个物种(多毛番茄)的短染色体区域对在渐渗到异源遗传背景(栽培番茄)中时相互作用的发生率。从15个染色体片段的完全双列杂交组合产生的105个双渐渗系(DIL)家系中,39个(约38%)在DIL F(2)群体中表现出以基因型和/或等位基因标记传递畸变形式存在的复杂上位性证据。
