Beware of genetic technology claims

"SEND US 2 ML SALIVA of your child and we will analyze his/her potential via DNA tests." That's a common sentence in the advertisements of many genetic testing companies, which have been doing brisk business of late. But people should be wary of such ads, says Workers' Daily:

Genetic technology is playing quite a positive role in the medical industry. Thanks to the technology, a pregnant woman can undergo embryo screening to find out what diseases her child might suffer from. This in turn could allow pharmaceutical companies to conduct research and make drugs that can be more accurately targeted at specific diseases.

But genetic technology is no fortuneteller - it cannot be used to test an embryo and forecast what sort of a person it will become as an adult or whether as an adolescent it will indulge in puppy love, as some companies claim.
