So, you think you know how Cinderella felt.
Many studies suggest that handedness is primarily a learned trait.
Genetic theories like Klar's contend instead that people are hard-wired for handedness in the womb. His study was published last month along with other papers presented at the 1996 Cold Spring Harbor Symposium on Quantitative Biology. He contends that those who inherit the gene, from either parent or both, are born right-handed. Klar calculates that 82 percent of people have at least one copy of gene, making them right-handed, while 18 percent lack it. There is a precedent in genetics for such a theory.
