| Abstract: | Abstract Lesbians, gay men, and bisexuals (LGBs) often have heterosexual siblings. The authors have conducted several research projects comparing siblings of different sexual orientations, given that siblings usually have the same ethnicity, race, parental socioeconomic status, and religious background. This review article presents research on LGBs and heterosexuals, all recruited via siblings. In general, heterosexual siblings are more mainstream in terms of being in long-term relationships, having children, belonging to a formal religion, and having more contact with their family of origin. LGB siblings are more politically liberal, more highly educated, and have moved away from their families of origin. The article speculates about how siblings who grow up in the same families could be so demographically different in adulthood. |
