a The 25 ESTP-s correspond to 11 gene loci.
b The SNPs markers correspond to 47 gene loci and 143 contigs.
c Markers with more than 70% of missing data (see Methods section) and identical markers.
d Assigned markers correspond to markers linked with more than 2 other markers.
e Unpositioned markers correspond to markers with a recombination frequency higher than 0.35 with the nearest linked marker (unlinked markers) or markers which position could not be reliably estimated. Percentage of positioned markers was calculated over the number of not excluded markers.
f Percentage of unlinked markers was calculated over the number of not excluded markers.
SD Standard deviation.
