The first planning meetings for a public-private haplotype map have barely finished and already the kinds of disagreements that occurred during the sequencing of the human genome appear to be surfacing. Most likely, there will be separate projects running in parallel using different methodologies to create different maps.

Haplotypes are groups of genetic variation (SNPs) that tend to associate together. The value of haplotypes lies in their ability to be used as markers for disease susceptibility or drug response.
