A dataset containing the pairwise recombinations fractions for 143 SNP markers from linkage group I of potato. These are derived from the genotypes of 190 offspring from a cross between potato cultivar Stirling and the breeding line 12601ab1. Further details are available in Hackett et al. (2013).
An ascii text file in the format described in calc.maps.pc
and calc.maps.sphere. The first line contains the number of markers
and the number of combinations. Then follow the space-separated combinations with
their recombination fractions and LOD scores:
nmarkers | |||
