Comparison of male and female genetic map length with truncated chromosomes.

“−30%”: correlation based on a truncated chromosome where 15% of the physical length at each extremity was removed. “−50%”: correlation based on a truncated chromosome where 25% of the physical length at each extremity was removed. p-value: probability that the observed discrepancy between Male and Female genetic map sizes be as large as it is under the hypothesis that their true values do not differ. p-value <4.81 e-09 for all of the comparisons.
