Thanks to College Jay for headline correction. He pointed out that they were not identical twins. I was thinking of another case with a similar result. The reference is here: Eckert, E. D., Bouchard, T. J., Bohlen, J. & Heston, L. L. (1986). Homosexuality in monozygotic twins reared apart. British Journal of Psychiatry. 148, 421-425.
