Localization of the lpk locus within chromosome 10. A. Position of the lpk locus (red) relative to polymorphic markers on chromosome 10 (shown in centiMorgan, cM) locations as analysed on the backcross 1 (BC1) generation, scoring the presence or absence of renal cystic phenotype. B. Sample gel for marker D10Mgh14 showing samples scored as homozygote LPK (B), homozygote Wistar Kyoto (A) or heterozygote (H).
