Scientists complete first phase of Hap Mapping

The Human Gnome Project mapped the three billion letters that make up the human genetic code.It showed that any two people are 99.9%the same. Now a group of scientists drawn from Britan,US,Canada,Japan,Nigeria and China has completed a detailed chart,showing markers of genetic variation,or single nucleotide polymorphisms(SNPs) to explain the 0.1 diffrence. The first phase contains more than 1 million SNPs. The second phase will add another 2 million. The first phase of the Hapmap has been published in the science journal Nature. The Hapmap provides scientist with indicators, with which they can focus on looking for genes involved in common diseases.
