In crosses 1 and 2, N_{2} females are heterozygous at D11Mit66. % of DDK represents the transmission of DDK alleles, in percent, at D11Mit66 from the heterozygous parent plus or minus the 95% confidence interval. χ^{2} is the value of the chi-square test under the null hypothesis of equal inheritance of alleles at D11Mit66 in each cross, except in cross 6 (#) where expectations were calculated on the basis of Wakasugi's (1974) predictions (see materials and methods). P is the level of significance, with n.s. denoting nonsignificance.
