A molecular linkage map for Antirrhinum majus Sippe 50 × 165E. The eight linkage groups are oriented, numbered and named as in previous Antirrhinum maps. Positions are given in centiMorgans (Kosambi). Protein-coding loci are named with their EMBL accession numbers as in Table 1 and with their Antirrhinum gene names in italics, where their functions are known from mutants. IDLE denotes a locus carrying an insertion of an IDLE transposon in one of the parents and loci with the suffix P are AFLP (see Materials & Methods for AFLP nomenclature). Loci with co-dominant alleles are shown in bold and those with dominant alleles in regular type.
