* The AFLP markers that anchor the contig belong to the same haplotype
** The AFLP markers that anchor the contig come from both haplotypes of the genome
*** Average length of the contigs (in kb) estimated from the number of fingerprint bands
**** Expected value when AFLP marker haplotypes combine independently in the BAC contigs
