Dataset lgV.txt: pairwise recombination fractions for 238 markers.

Description

A dataset containing the pairwise recombinations fractions for 238 SNP markers from linkage group V 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).

Format

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
marker_1	marker_2	recombination fraction	LOD

1	3	.	.
