We describe a method for identifying, from a comprehensive genetic map, the
most dense framework of confidently ordered markers. The approach uses the
number of observed recombination events between each pair of markers, and
finds the largest subset of markers for which adjacent loci are separated b
y at least one recombination. We illustrate the approach using a short regi
