a A refers to the first locus in the pair, and B refers to the second locus. The uppercase letter refers to Rps2, Rmd-c, Rj2, or Ti-a, and the lower case refers to rps2, rmd, rj2, or Ti-b.
b Probility of a greater chi-square value due to chance deviation from independent assortment.
c Recombination frequency.
d Standard error of the recombination frequency.
