SCIENTISTS MAY HAVE FALLY UNLOCKED PUZZLE OF WHY PEOPLE ARE GAY

A group of scientists suggted Tuday that homosexuals get that tra om their oppose-sex parents: A lbian will almost always get the tra om her father, while a gay man will get the tra om his heredary lk of homosexualy has long been tablished, but scientists knew was not a strictly geic lk, bee there are many pairs of intil tws who have differg sexuali. Scientists om the Natnal Instute for Mathematil and Blogil Synthis say homosexualy seems to have an epigeic, not a geic thought to have some sort of heredary lk, a group of scientists suggted Tuday that homosexualy is lked to epi-marks — extra layers of rmatn that ntrol how certa gen are exprsed.

"There is pellg evince that epi-marks ntribute to both the siary and dissiary of fay members, and n therefore feasibly ntribute to the observed faial herance of homosexualy and s low nrdance between [intil] tws, " Rice and his team created a mathematil mol that explas why homosexualy is passed through epi-marks, not geics. " Homosexual behavr has been observed black swans, pengus, sheep, and other animals, he 's mol still needs to be tted on real-life parent-offsprg pairs, but he says this epigeic lk mak more sense than any other explanatn, and that his team has mapped out a way for other scientists to tt their work. Yet same-sex attractn is wispread humans, and rearch suggts that is partly a study of data om hundreds of thoands of people, rearchers have now intified geic patterns that uld be associated wh homosexual behavur, and showed how the might also help people to fd different-sex mat, and reproduce.

Most of the participants were born durg a time when homosexualy was eher illegal or culturally taboo their untri, so many people who were attracted to others of the same sex might never have actually acted on their attractn, and uld therefore have end up the wrong group the Monk, an elogist and evolutnary blogist at Yale Universy New Haven, Connecticut, thks that the veats are so important that the paper n’t draw any real nclns about geics and sexual orientatn.

LBIAN AND GAY PARENTG

Unlike heterosexual parents and their children, however, lbian and gay parents and their children are often subject to prejudice bee of their sexual orientatn that n turn judg, legislators, profsnals, and the public agast them, sometim rultg negative out, such as loss of physil ctody, rtrictns on visatn, and prohibns agast adoptn (ACLU Lbian and Gay Rights Project, 2002; Appell, 2003; Patterson, Fulcher, & Waright, 2002).

The relevance of this cricism has been greatly rced as rearch has expand to explore life a wir array of lbian mother and gay father fai (many of which have never lived through the divorce of a heterosexual uple), and as newer studi beg to clu a wir array of ntrol groups.

Other cricisms have been that most studi have been based on relatively small sampl, that there have been difficulti wh asssment procr employed some studi, and that the classifitn of parents as lbian, gay, or heterosexual has been problematic. An expert readg of the Sarantakos article reveals that certa characteristics of s methodology and sample are highly likely to have skewed the rults and renred them an valid ditor of the well-beg of children raised by gay and lbian parents at least three rpects:. The children raised by gay and lbian parents experienced unually high levels of extreme social ostracism and overt hostily om other children and parents, which probably acunted for the former's lower levels of teractn and social tegratn wh peers (see pp.

WHY GAY PARENTS MAY BE THE BT PARENTS

Some nonscientific anizatns have attempted to nvce urts that there is an actual scientific dispute this area by cg rearch performed by Pl Cameron as supportg the existence of fics gay and lbian parents or their children pared to heterosexual parents or their children. Three ncerns have historilly been associated wh judicial cisn makg ctody ligatn and public polici erng foster re and adoptn: the belief that lbians and gay men are mentally ill, that lbians are ls maternal than heterosexual women, and that lbians' and gay men's relatnships wh sexual partners leave ltle time for ongog parent-child teractns (ACLU Lbian and Gay Rights Project, 2002; Falk, 1989, 1994; Patterson et al., 2002; Patterson & Reddg, 1996).

Many years ago, the Amerin Psychiatric Associatn removed "homosexualy" om s list of mental disorrs, statg that "homosexualy per se impli no impairment judgment, stabily, reliabily, or general social or votnal pabili" (Amerin Psychiatric Associatn, 1974). The cisn to remove homosexual orientatn om the list of mental disorrs reflects extensive rearch nducted over three s showg that homosexual orientatn is not a psychologil maladjtment (Gonsrek, 1991; Hart, Roback, Ttler, Wez, Walston, & McKee, 1978; Reiss, 1980). There is no reliable evince that homosexual orientatn per se impairs psychologil functng, although the social and other circumstanc which lbians and gay men live, cludg exposure to wispread prejudice and discrimatn, often e acute distrs (Cochran, 2001; Freedman, 1971; Gonsrek, 1991; Hart et al., 1978; Hooker, 1957; Meyer, 2003; Reiss, 1980).

THERE IS NO ‘GAY GENE.’ THERE IS NO ‘STRAIGHT GENE.’ SEXUALY IS JT PLEX, STUDY NFIRMS

Beliefs that lbian and gay adults are not f parents likewise have no empiril foundatn (Anrssen, Amlie, & Ytteroy, 2002; Brewaeys & van Hall, 1997; Parks, 1998; Patterson, 2000; Patterson & Chan, 1996; Perr, 2002; Stacey & Biblarz, 2001; Tasker, 1999; Victor & Fish, 1995). A recent study of 256 lbian and gay parent fai found that, ntrast to patterns characterizg the majory of Amerin parents, very few lbian and gay parents reported any e of physil punishment (such as spankg) as a disciplary technique; stead, they were likely to report e of posive techniqu such as reasong (Johnson & O'Connor, 2002).

Certaly, rearch has found no reasons to believe lbian mothers or gay fathers to be unf parents (Armto, 2002; Barret & Robson, 1990; Bigner & Bozett, 1990; Bigner & Jabsen, 1989a, 1989b; Bos et al., 2003, 2004; Bozett, 1980, 1989; Patterson, 1997; Patterson & Chan, 1996; Sbordone, 1993; Tasker & Golombok, 1997; Victor & Fish, 1995; Wton, 1991).

For stance, one such ncern is that children brought up by lbian mothers or gay fathers will show disturbanc genr inty and/or genr role behavr (Falk, 1989, 1994; Hchens & Kirkpatrick, 1985; Kleber, Howell, & Tibbs-Kleber, 1986; Patterson et al., 2002; Patterson & Reddg, 1996). For example, urts have exprsed fears that children the ctody of gay or lbian parents will be more vulnerable to mental breakdown, will exhib more adjtment difficulti and behavr problems, and will be ls psychologilly healthy than other children. Three aspects of sexual inty are nsired the rearch: genr inty, which ncerns a person's self-intifitn as male or female; genr-role behavr, which ncerns the extent to which a person's activi, occupatns, and the like are regard by the culture as mascule, feme, or both; and sexual orientatn, which refers to a person's choice of sexual partners, who may be homosexual, heterosexual, or bisexual (Money & Ehrhardt, 1972; Ste, 1993).
