Speeding within the Re Search Process
In 2015, there have been about one million individuals on Ancestry.com. Presently there are about nine million. Other web web web sites like GEDmatch and 23andMe have become at comparable prices, that makes it less difficult to utilize DNA to get an unknown that is relative to spot a suspect.
“It’s a whole various landscape for doing analysis in unknown-parentage cases,” said Dr. Rae-Venter. She estimated that the seek out Lisa’s identification, which took her as well as other volunteers 20,000 hours three years ago, could now be performed in only 2 days on her very very own.
