If I had a baby on the way, like any prospective parent, I’d want my kids to be healthy.

Scientists have mapped a full fetus genome using blood and saliva from the parents. When compared to genetic screening results taken after birth, the results were a 98% match.

This could lead to genetic tests in early pregnancy, which would be safer than current ones. But scientists are cautious, as lots of ethical issues would be raised too.
