Figure 1

Observed distribution of inter-crossover distances compared to theoretical gamma distributions corresponding to the Haldane and Kosambi map functions. Inter-crossover distances are shown in the histogram; Haldane map functions as the green line and Kosambi map functions as the red line. The dashed black line represent the gamma function fitted to the observed distribution through a maximum likelihood approach. The blue line is the gamma(ν, 2ν) distribution fitted to the observed data. The blue and red lines are almost coincident.
