  1. a The map constructed by nnTwoOpt, where nearest neighbor was used for tour construction, and two-opt was used for tour improvement
  2. b The map with the same marker order of the physical map
  3. c The map using the first replication of genotyping
  4. d The map using the second replication of genotyping
  5. e The map using the non-erroneous genotypic data, i.e., all inconsistent genotypes between the two replications of genotyping are replaced by missing values
