Researchers at the University of Washington have mapped the genome of a baby in the womb. They did it by giving the mom a blood test and dad a non invasive saliva swab.
What makes this significant is the test is easy and could one day allow fetuses to be screened for more than 3,500 genetic disorders.
It could become an alternative for riskier more invasive methods now used to determine if a fetus is genetically predisposed to disease.
This also brings a host of ethical questions with concerns an easier test could lead to more abortions.
