Mapping of the Plt1 mutation. A cohort of 329 (C57BL/6-BALB/c) × C57BL/6 N2 mice was used to map the Plt1 mutation. The genotype of key markers on chromosome 6 is shown (filled boxes, loci that are homozygous for C57BL/6 homozygous allele; open boxes, loci that are heterozygous), demonstrating that the mutation lies in a 6.5-Mb interval between D6Mit139 and D6Mit83.
