Shown are the marker number, linkage size (cM), and marker density of each linkage group. LG24 was the shortest LG, comprising only 13 loci, whereas LG01 was the longest, spanning 159.9 cM and containing 224 loci with a marker density of 0.7 cM/locus (map unit determined by Haldane’s distance while for other LGs Kosambi’s was used)
