(Fortune Small Business) -- When Bill Gates's children become adults, they'll probably launch their own businesses.
And not just because of their father's example. Entrepreneurial tendencies -- including the ability to recognize business opportunities -- are heavily influenced by genetic factors, according to a study co-directed by Scott Shane, a professor of entrepreneurial studies at Case Western Reserve University.
Shane and his fellow researchers compared the entrepreneurial activity of 870 pairs of identical twins -- who share 100% of their genes -- and 857 pairs of same-sex fraternal twins -- who share 50% -- to see how much of entrepreneurial behavior is genetic and how much is environmental.
