Two-locus comparison between ME2 and GOT2 from the cross of ABf x SDm.

The relative contributions for the two-locus genotypic class combinations at ME2 and GOT2 to deviations from independence for F₂ adult hybrids from the AB and SD populations of T. californicus are shown. The bars indicate the χ² deviation contributed by each two-locus genotypic class for each of two temperature environments. A positive value indicates that more individuals in that class were observed than expected while a negative value indicates that less were observed than expected. The expected distributions under two different models of three-locus DM incompatibilities can be seen in Figure 6 with other two-locus models explored in Willett [42].
