Multifaceted, Cross-Generational Costs of Hybridization in Sibling Drosophila species
Figure 4
Proportion of adult flies eclosing from parental species (PS), F1 hybrid (F1) or backcross progeny (BC) classes (+/- 1 SE) larvae in competition with larvae from the mutant OR-PX at three competition levels. The parental species are superior competitors to both hybrid and backcross larvae against the weak competitor. PS values are averaged across the F1 and BC experiments.
