Haplotype data for the mapping of the mouse CPβ gene showing a portion of Chromosome 4 with loci linked to Cappb1. Loci are listed in order with the most proximal at the top. The black boxes represent the C57BL6/J allele and the white boxes the SPRET/Ei allele. The number of animals with each haplotype is given at the bottom of each column of boxes. The percent recombination (R) between adjacent loci is listed to the right, with the standard error (SE) for each R. Missing typings were inferred from surrounding data where assignment was unambiguous.
