Rapid Evolution of Assortative Fertilization between Recently Allopatric Species of Drosophila
Figure 1
Egg hatch rate within and between D. novamexicana and six lines of D. americana(see Section 2). Egg hatch estimates “within N line” and “within A lines” are averages of within-line hatch rates from all experiments. Asterisks indicate egg hatch estimates that are significantly different between lines compared to within lines (, Tukey-Kramer HSD). A = D. americana, . novamexicana. N4 is the D. novamexicana line used throughout the study (1031.4). All remaining two-letter abbreviations are the first two letters of each D. americana iso-female line i.d. (see Section 2).
