SNP genetic and physical position. For each chromosome, the map on the left (gray bars) shows the physical position of studied SNP markers on the 12X grapevine sequence of the PN40024 near homozygous line  indicated in kilobases; and the map on the right (empty bars) shows the genetic position, indicated in centiMorgans, of microsatellites (between brackets) and SNP genetically mapped using the four segregating progenies. Markers with known position in only one of these maps are indicated in bold: in the map on the left, the SNP with known physical position that could not be mapped genetically; and in the map on the right SNP mapped genetically but with unknown or uncertain physical position.
