(A) Homozygosity mapping in Israeli Bedouin Kindreds 1 and 2 (DFNB11). Selected affected individuals from kindreds 1 (K1), 2A (K2A), and 2B, (K2B), described by Scott et al. (1995), are shown with their corresponding haplotypes. Bold genotypes and lines define the region of homozygosity shared across both kindreds. All affected individuals are homozygous at markers D9S1822, D9S1837, andD9S1876, and the DFNB11 interval is bounded byD9S1806 (centromeric) and D9S769 (telomeric). (B) Homozygosity mapping of individuals from Indian family 1B (DFNB7), as described by Jain et al. (1995) with the centromeric boundary at D9S166. (C) Pedigree of family TM with haplotypes shown below. Homozygosity by descent is present fromD9S15 to beyond D9S276. Individual III defines the telomeric boundary with a recombination event at D9S769.
