Figure 1. Pedigree drawings with haplotype formed from alleles of chromosome 6p microsatellite markers. A: PKRP259. B: PKRP268. C: PKRP301. D: PKRP309. E: PKRP356. F: PKRP364. G: PKRP367. The alleles forming the risk haplotype are shaded black, and the alleles that do not cosegregate with retinitis
pigmentosa (RP) are shown in white. Squares = males; circles = females; filled symbols = affected individuals; double line
between individuals = consanguineous marriage; diagonal line through a symbol = deceased family member.
