  1. The overall female:male recombination ratio was 1.68:1, with the female having a map length of 4,317.60 cM and the male map 2,564.10 cM. However, individual chromosome and regions of chromosomes varied, with a range of .73:1 to 12.22:1. This table shows the sum of sex averaged (r total), female (r F) and male (r M) recombination fractions between adjacent pairs of loci and the ratio of female to male (F:M). In some cases the sex-averaged recombination rate is lower than that for either of the sexes, this is because different sets of loci are informative for each analysis.
