First genome of woman

Dutch scientists claim they have completed the first sequencing of an individual woman's DNA.

The researchers at Leiden University Medical Center say they have sequenced the entire genome of one of their female researchers, though no other scientists have yet verified their data.

The first sequencing of a composite human genome was announced in 2001. Four individual male genomes have so far been sequenced. Scientists have also mapped the DNA of about a dozen mammals, including chimpanzees, dogs, cats, cows and a platypus.
