Two‐point methods were used throughout. Male and female lod scores were calculated using LIPED. Edwards' programs, ZLODS and OBM, were used for joint analysis of the lod scores. ZLODS estimates recombination fractions. OBM calculates the likelihood and estimates the map distances for a given ordering of loci. Since OBM will only analyze a specified ordering, multidimensional scaling was used as a general method for establishing linkage groups and likely orderings within them.
