We are each more unique than originally thought. For the first time, scientists have fully mapped the genome of an individual. The breakthrough promises to advance research into genetic disorders and treatments. However, the finding that previous genetic mapping had underestimated genetic diversity will add complexity to that research. Scientists say that by sequencing more individual genomes greater insight will be provided into how genes define human attributes. Sequencing individual genomes has been simplified, and made more cost effective, by technological advances. The hope is that ultra-fast sequencers could allow an individual genome to be sequenced for $1000.
