  1. The mean (and SE) are reported for 100 simulations of a 100 cM interval containing 1000 markers. Linkage maps were generated from doubled haploid populations of 200 offspring, using parents with 70% sequence identity. Results are shown for both the LP and QP methods of linearizing the consensus graph (error was calculated after rescaling).
