Figure 2. Genetic map of Linkage Groups I, O, and L for the FAF population (N97-3363-3 x PI423893) constructed with JoinMap 3.0. The estimated locations of FAD2-1A, FAD2-2A, and FAD2-2B are presented. It should be noted that mapping of FAD2-2B on Linkage Group L in the FAF population is not in agreement with linkage analysis in the FAS population. The FAD2-2B isoform probably maps within the interval of the simple sequence repeat markers sat_340 and satt006 on Linkage Group L, as indicated by the linkage map of FAS population (N98-4445A x PI423893). The FAD2-2A isoform also colocalizes with FAD2-2B on Linkage Group L. Genetic distances were estimated with Kosambi's mapping function. Linkage groups were drawn on an equal scale.
