Replication refers to finding the same or similar results in a research study. Peter LaBarbera says lack of replication is a problem for genetics studies of homosexuality. Inconvenient for LaBarbera is the fact that the new study, which he claims to know something about, replicates the finding of linkage at Xq28. While it is true that prior efforts have been mixed regarding Xq28, there has been prior support for the region and this study found linkage there. Thus, this study replicated prior studies, including the work of Dean Hamer.
I would be willing to bet Mr. LaBarbera has not read the study. If he had, he would know that he told ONN something opposite of the truth.
