Fig. 1. Chromosomal organization of the raz mutation. (A) Results of DNA typing of backcross progeny. Markers shown from chromosome 5 are those that have been typed on 553 backcross DNAs. Values at the bottom of the figure are the number of progeny inheriting the indicated chromosome haplotype from the F1 parent. White squares represent the C3H/HeJ allele; black squares represent the BALB/c allele. (B) Ideogram of chromosome 5. Representation of the microsatellites used for linkage analysis with their physical and genetic positions. Also shown are genes involved in limb morphogenesis that are located within the inversion.
