↵a Pairs of crosses were compared using the t-test. Values in parentheses are P-values.
CI is reported as percentage embryo mortality ±SE. Experiments for each Drosophila species were performed simultaneously. Crosses 2, 4, and 6 represent the pool of both transinfected lines of each species since there was no intraspecies difference between the lines.
