  1. LG = M. truncatula Linkage Group A dominant marker is considered as a male marker if the recessive allelic form is male (and the same for female). χ2 for equality of number of male and female dominant markers = 1.729 χ2 for equality of number of male and female distorted markers = 0.077 Tabulated χ2 for degrees of freedom = 1 is 3.84 at P = 0.95 level of significance.
