To add to Dr. Bradshaw's sage advice, a detailed description of the use 
of MAPMAKER for haploid linkage analysis can be found in:
Plomion et al. (1995) Genomic analysis in maritime pine (Pinus 
pinaster). Comparison of two RAPD maps using selfed and open-pollinated 
seeds of the same individual.  Theor Appl Genet 90:1028-1034.
