  1. For each linkage group and the whole genome (total) are indicated: the number of markers mapped (1,346 for family B alone, 128 for family V alone, 534 for both); the genetic length of the map: Haldane and Kosambi functions of distance calculated on the combined map (B + V) (the Kosambi function is used for the calculation of the ratios in the other columns); and the number of recombinations for families B and V normalized by progeny numbers; the density of markers (calculation including null distances) - the density is homogeneous for all chromosomes except 15 and 16 which were further worked for superscaffolding assistance (see text), all distances are smaller than 10 cM; the number of scaffolds that were integrated in assembly version 4.0 with AmelMap3 as the framework; the physical length of the scaffolds in assembly 4.0; the recombination rate as a ratio of the genetic length in centimorgans (cM) over the physical length in megabases (Mb). interference: shape parameter of the fitted gamma(ν, 2ν) distribution.
