Easier said than done. Monozygotic twins appear in only about 3 of every 1,000 births. Women are more likely to have twins if they're of West African ancestry, of greater than average height and weight, and already mothers.
But identical twins are not really identical.
Life experiences -- differences in activity, nutrition, exposure to contaminants -- result in more changes, even at the genetic level.
Unless they work at it, identical twins stop looking identical by adulthood.
I've never met a pair of gay identical twins, but here's some pictures. Notice the differences in face and physique.
At least the beneath-the-belt gifts look the same.
I should mention MZ are the same frequency in any racial group. DZ are more frequent in West Africa, and more frequent still in fiction. (As part of that "nuclear family" nonsense.)
ReplyDeleteThere's also the question of if they'll go for it. And yes, I know, "hetero cultural norms don't really apply". (I'm limiting this discussion to brothers and cousins: Intergenerational incest is a road, you don't want to go daown that rod. It was built on an Indian burial graound, but it was cursed even befar that, which is why the Indians stopped buryin' their dead thar. Man killed his family thar back in '38. Then in '67, a bus full o' nuns was killed in a rockslide. Then in the summer of '89, four girls went missin'. Lot o' hist'ry on that rod.) But, like, I've known the whole gamut of brothers. I wouldn't do a thing with my brothers. But other guys have masturbated with their brothers, even "straight" guys. Still others have had penetrative sex with their brothers. Still others still do. The idea of a three-way with your brother is a whole other thing, usually more palatable. Unsurprisingly, I brothers more likely to screw each other had porn careers.
But brothers are still the rarity.
An aside, I question any reductionist "one-gene" hypothesis about being gay, of course; life is the interaction between genes and the environment. (Which doesn't make being gay a choice either, any more than the color of my skin is a choice.) Then again, bigots have never listened to science anyway, and given that the Nazis among others really thought it was hereditary and this something that could be bred out, I'd wager that "gay genes" aren't likely to win hearts and minds anyway.
I've heard more father-son than brother-brother incest fantasies, but they get mixed up with the fact that younger guys call everyone over 40 Daddy. I get so sick of going on Grindr and getting a dozen "I've been naughty, Daddy!" comments.
DeleteTrue, but that's the problem, isn't it? Daddy issues.
DeleteDid you like my hayseed dialect, though?
