Researchers use blood from the mother and saliva from the father to determine a fetus' entire DNA sequence. If refined, the technique could provide a risk-free way to screen for genetic disorders. Scientists have pieced together the entire DNA sequence of an 18-week-old fetus without having to use any invasive tests that could result in a miscarriage — an advance that offers a glimpse of the future of prenatal testing.
