Fig. 3From: Genetic analysis of the barley variegation mutant, grandpa1.aGenetic and physical mapping of the Gpa1 locus. Genetic mapping was conducted sequentially with 104 (a) and 510 (b) F2 individuals. Gpa1 is located on 2H, delimited to an ~ 0.7 cM region between markers M19 and M8 (b). Total of 15 protein-coding genes were identified in the Gpa1 region spanning ~ 400 kb (c). Numbers above the linkage group indicate the number of recombination breakpoints separating the marker from Gpa1. The maps are drawn to scale. M, marker; G, geneBack to article page
