Human Genome Mapped, but DNA Still a Mystery
Genes more complex than scientists thought

(Newser) – A new map of human DNA shows just how complex we really are – so much so that scientists can’t even pin down which genes are making our eyes blue. "I found out that I have [only] a high probability of having blue eyes," says azure-eyed biologist Craig Venter, whose genetic code is published in a new study. "We all thought that would be simple."

Researchers spotted 4.1 million places where Venter’s DNA differed from the human genome mapped in 2001, Reuters reports. Whatever the results, Venter says he hopes they help people overcome their fears of genetic sequencing. “"Knowing something doesn't change what's in our genetic code. But knowing things maybe gives us a chance to change what could be part of our genetic destiny.”
