- These studies show that there is no scientific data to support a genetic or biologic basis for same-sex attractions.
This statement doesn't logically follow the findings of these studies; which have shown that 1) there is a possible sexual-orientation dimorphism (difference in the size of a part of the brain), 2) the sexual orientation of identical twins seems to follow a predictable pattern once the orientation of one twin is known, and 3) there is a cetain gene that tends to follow individuals who identify as homosexual. --maveric149
In addition, the current title of the article misses the point -- only one of these studies really deals with genetics. The other two deal with phenotypes and behavior -- which arise from varying degrees of interaction between genes, the chemical environment of the body, the outside environment, self-identification, etc. A MUCH better title would be innate basis of sexual orientation. If there is such a thing as a 'gay gene' (or more likely genes) there is every reason to believe that it/they has/have only some degree of influence on sexual orientation that is somehow "set" in early to late adolescence (thus its supposed "innateness"). Many other factors are probably also at play. --maveric149
