title: A genetic map of index DNA loci on bovine chromosome 21.
abstract: Genetic maps of highly polymorphic index DNA loci exist essentially only in humans and some experimental organisms. Here we report the first genetic map of highly polymorphic index DNA loci in livestock for bovine chromosome 21. This map consists of six loci with an average heterozygosity of 82%, each with a minimum of five alleles, spaced at an average genetic distance of 9.7 cM, and covers most of the expected length of the acrocentric bovine chromosome 21. The order of markers along the chromosome is cen-ETH 131-UWCA 4-TGLA 337-TGLA 122-CSSM 18-GMBT 16-tel. There is heterogeneity among the recombination fractions between the sexes.
