Figure 2

Recombination distance plotted over the Kosambi distance for chromosomes 1 to 16. The recombination distance is directly deduced from allelic phase changes on the map. Note that for chromosome 7 the individual points are superimposed on the diagonal (Kosambi on Kosambi), for chromosome 13 the recombination rate decreases progressively in the distal half, and for chromosome 8 the decrease is central.
