  • Introgression lengths are in numbers of polytene bands (mean ± SD). The introgression lengths on the two chromosomes are very different for all four classes (t-test, P ⪡ 0.001 for all classes). Data of the X chromosome are compiled from Perez et al. (1993), Figure 4; Cabot et al. (1994), Figure 5; Perez and Wu (1995), Figure 2; Davis and Wu (1996), Figure 3.
