Homosexuality and Genes...

Just finished reading this in my psychology book - found it very interesting and though I would share:

"Research as shown that differences in sexual orientation have a genetic basis.  For example, Bailey and Pillard (1991) studied a group of male homosexuals who had twin brothers, and they found that 52% of the monozygotic (identical) twin brothers and 22% of the dizygotic (fraternal) twin brothers were homosexual.  In a comparable study of female twins by the same group of researchers, the concordance rates for homosexuality were 48% for monozygoticd  (identical) twins and 16% for dizygotic (fraternal) twins."
