The goal of the First International Equine Gene Mapping Workshop, held in 1995, was the construction of a low density, male linkage map for the horse. For this purpose, the International Horse Reference Family Panel (IHRFP) was established, consisting of 12 paternal half‐sib families with 448 half‐s

Summary
A low‐density, male‐based linkage map was constructed as one of the objectives of the International Equine Gene Mapping Workshop. Here we report the second generation map based on testing 503 half‐sibling offspring from 13 sire families for 344 informative markers using the crimap program. The multipoint linkage analysis localized 310 markers (90%) with 257 markers being linearly ordered. The map included 34 linkage groups representing all 31 autosomes and spanning 2262 cM with an average interval between loci of 10.1 cM. This map is a milestone in that it is the first map with linkage groups assigned to each of the 31 automosomes and a single linkage group to all but three chromosomes.

We report the fine mapping of 55 of our 95 amber mutations in the β gene of __Escherichia coli__ RNA polymerase by virtue of the unique __Mae__I restriction sites created by this subset of nonsense mutations (i.e. CTAG, where the amber codon is underlined). [The full data are reported in Supplementa
