On this basis, they claim that "homosexuality is genetic From Science, 1994: Time and time again, scientists have claimed that particular genes or chromosomal regions are associated with behavioral traits, only to withdraw their findings when they were not replicated. Joel] Gelernter, "it's hard to come up with many" findings linking specific genes to complex human behaviors that have been replicated. All were announced with great fanfare; all were greeted unskeptically in the popular press; all are now in disrepute. The author of the lead article on genes and behavior in a special issue of Science speaks of the renewed scientific recognition of the importance of environment. Homosexual Twin Studies Two American activists recently published studies showing that if one of a pair of identical twins is homosexual, the other member of the pair will be, too, in just under 50% of the cases He notes the growing understanding that: . The same data that show the effects of genes, also point to the enormous influence of nongenetic factors. More Modest Claims to the Scientific Community Researchers' public statements to the press are often grand and far-reaching. But when answering the scientific community, they speak much more cautiously. He replied: "Absolutely not. Our studies try to pinpoint the genetic factors. But in qualifying their findings, researchers often use language that will surely evade general understanding making statements that will continue to be avoided by the popular press, such as: . Sounds too complex to bother translating? This is actually a very important statement. From twin studies, we already know that half or more of the variability in sexual orientation is not inherited In layman's terms, this means: It is not possible to know what the findings mean--if anything--since sexual orientation cannot possibly be inherited in the direct way eyecolor is.
