Effect of sequence diversity between parental accessions on genetic map lengths. (a) The number of SNPs along chromosomes 2–5 between each pair of founding accessions, plotted as a function of the number of SNPs along chromosome 1. R²-value for the multiple linear regression is 0.65 (P=3.5e−15). (b) Total genetic map length in cM as a function of the total number of SNPs between founding accessions. R²-value is 0.04 (P=0.56). (c) Chromosome length in cM as a function of the number of SNPs between founding accessions. R²-value for the multiple linear regression is 0.48 (P=1.15e−13). (d) Chromosome length in cM as a function of SNP density (per kb). R²-value for the multiple linear regression is 0.002 (P=0.01).
