With all this tasting of DNA, to find where you came from, there is the dark side. Just try to imagine the horror / shock / divorce that occurs when a child finds out that the man she/he calls dad, isn't their biological father. Term for it is NPE (not parent expected.) Something I have never understood, is when a pregnant woman is murdered, why DNA isn't taken from the fetus. If the fetus's DNA doesn't match father's then that brings in a new list of suspects, or it may be the reason spouse committed murder in first place. Several years back, we had such a case here. Woman found dead, pregnant, and know to be having an affair. Somebody other than her spouse could have wanted her dead. No positive evidence to convict husband, but he served time while awaiting appeals. In appeals, wound up with a sentence of time served. It was a case of heads the state wins, tails, the accused loses.
