*P*< 0.0001 based on χ^{2}tests of observed frequencies*vs.*the Mendelian expectation with 2 d.f. for genotypes and 1 d.f. for allele frequencies. O, observed; E, expected.↵a O allele frequencies are reported as

*M. guttatus*:*M. nasutus*(G:N). At*hms2*, but not*hms1*, allele frequencies significantly differ from the Mendelian expectation (0.5:0.5).↵b O and expected E genotype frequencies are reported as

*M. guttatus*homozygotes:heterozygotes:*M. nasutus*homozygotes (GG:GN:NN). Expected genotype frequencies shown are calculated from the random union of gametes with the observed frequencies. At*hms1*, genotypes differ significantly (*P*< 0.0001) from both the Mendelian expectation (0.25:0.5:0.25) and from the expectation given the random union of gametes with the observed allele frequencies. At*hms2*, genotypes differ significantly (*P*< 0.0001) from the Mendelian expectation but not from the expectation given the random union of gametes with the observed allele frequencies.
