His first look at the issue is his evaluation of LeVay's experiment. Terry believes the information about the different sized neutrons is interesting, yet doesn't jump to form any opinion based on it. Whether this resulted from natural biological causes or from environment or other reasons has not been determined thru scientific analysis. Terry doesn't make the mistake here of suggesting a false dilemma that the different neurons have to be caused by either nature or nurture. He stays open to other options that may be unknown.
Terry then comments about the experiment involving the identical twins.
Unfortunately, he claims that fifty-two percent of identical twins will both be gay. Robertson stated that sixty percent was the correct number. Because both of these men failed to sight their sources in their articles, I am unable to tell whether this is a flaw in one of their calculations, if the information was recorded at different times or if the study was a completely different one altogether. Terry doesn't claim that the coincidences in identical twins proves that homosexuality is or isn't genetic. After the scientific proof, Terry gets into the influences of the Bible and how they relate to the possibility of genetic homosexuality.
