SNP imagemap. Reference markers for the integrated map, which are from the CHLC/ABI Prism version 1 reference map (http://www.chlc.org/ABI/ABIRefMaps.html), are linked to CHLC annotation. Genetic map positions of reference markers, in red text, are to the right of the genetic map. Physical map positions of these markers, also in red text, are to the left of the physical map. Reference markers that have not been physically mapped are assigned the radiation hybrid map position of a closely linked proxy marker, indicated by a star next to the physical map position. Clicking on a starred physical map position opens a web page containing information about proxy markers. Numbers in boldface to the left of the genetic map denote genetic map intervals. The histogram to the left of the genetic map indicates the number of candidate (orange), validated (red), and confirmed (purple) SNPs mapping to each map interval. Clicking on a histogram bar opens an HTML summary page listing SNPs genetically and/or physically localized to that map interval. Physical map intervals are hyperlinked to web pages displaying the position of UniGene clusters with SNPs on the Genebridge4 radiation hybrid map. PCR primer set identification numbers of physically mapped; confirmed SNPs are located to the right of the physical map. Color coding is as follows: green (the physical map position lies within the best genetic mapping interval); blue (the physical map position lies within the likely genetic mapping interval); red (the physical map position lies outside the best and likely genetic mapping interval; not shown). PCR primer set identification numbers and the genetic map diagram are linked to the linkage imagemap web page (Fig. 2). Ideograms on are based on coordinates from Francke (1994).
