SOUMYA Swaminathan’s 16-year-old son, Sudarshan, loves sports, and is training to be a footballer. Two years ago, he was confused which sport to train in. “He would come home and say he wants to play cricket. Next week it would be football,” says Swaminathan. Then she heard about the sports DNA test offered by Super Religare Laboratories (SRL). The Mumbai-based firm had just launched the test, which would examine DNA from your saliva sample for variants of a gene linked with sporting prowess. It turned out that Sudarshan had a genetic predilection for power sports.
