Alexandra Burt, PhD, of Michigan State University asserts that "The idea is that your genes predispose you to certain behaviors, and those behaviors elicit different kinds of social reactions from others," Burt said in a news release. "And so what's happening is your genes are to some extent driving your social experiences."
Studies of a gene that affects brain levels of the chemical messenger serotonin (the 5HT2A serotonin-receptor gene) are supporting this theory.
Sightist assembled more than 200 college men with an average age of 19 into two groups. One group met together to plan a party on a strict budget; the other met to plan a party for which the sky was the limit. Immediately after the planning session, individuals rated their peers on popularity. They also gave a DNA sample.
"So the gene predisposed them to rule-breaking behavior, and their rule-breaking behavior made them more popular," Burt says.

Last researches have showed that a genetic test might determine which sports, like sprinting or football, or endurance sports like distance running, or a combination of the two, maximally suit the talents of your 2 ½-year-old kids? 
“I could see how some people might think the test would pigeonhole your child into doing fewer sports or being exposed to fewer things, but I still think it’s good to match them with the right activity,” Ms. Campiglia, 36, said as she watched a toddler class at Boulder Indoor Soccer in which Noah struggled to take direction from the coach between juice and potty breaks.
“I think it would prevent a lot of parental frustration,” she said.
It was discovered the link between ACTN3 and athletics. Actually the process of testing is very easy. Dr. Roth called ACTN3 “one of the most exciting and eyebrow-raising genes out there in the sports-performance arena,” but he said that any test for the gene would be best used only on top athletes looking to tailor workouts to their body types.
