CHICAGO TRIBUNE - Oct 15 - Claudia Haase, an assistant professor in Northwestern University's School of Education and Social Policy says that the formula - Two People + DNA Test = Marital Bliss - is a misinterpretation of the research. "There's no perfect match," she said. "It really depends on the particular couple, and on what you want." There's a gene called 5-HTTLPR (Love Gene) however, which is involved in the body's regulation of the hormone serotonin, which can lead to feelings of happiness. The study found that the length of one's Love Genes can predict how emotions will affect a relationship. A person who has two shorter Love Genes tends to feel the highs and lows of marriage more deeply.
