Questions about gay twins?

I have heard about scientific studies and psychoanalyzes of twins as a method to learn about genetics of homosexuality. If you support that homosexuality is completely genetic then wouldn't it be uncommon that both twins be gay? Regardless of being twins suppose about 1 child in every 10 is born gay. So 2 children by the same parent both being gay has many odds stacked against them.

In the case of identical twins perhaps the genetic information that determined the orientation of that child (originally intended to only be 1 individual) was present before the embryo split up and became 2. But then how does one explain identical twins who have different orientations?

One thing with genetics and the human mind though, nothing is certain, it's probably a complex combination of factors and forces throughout development that determine the overall expression of an individual's sexuality.

I am a fraternal twin, I am a gay male and my sister is a straight female.

I know a pair of identical twins (women). Both are lesbians.

i know 2 fraternal twins. a set of boys and a set of girls. 1 of the 2 boys is gay... and th other one is straight. and for the girl i don't really know. i know one is straight and the other one is "bi".... i don't know if she's really bi or if she's just saying that

yeah i know these identical twins, one is gay and the other is straight

i got tegan and sara.i don't really know any,but i heard that twins have a 15% higher chance of coming ot gay,but i don't really know

I was a lesbian intil I found the joy of sex. Werid but true. My twin died 2 days later because her heart stoped and it was a clog up. I was 2 days old and my mother was very upset about how I am and what I do to myself. Yet I can't let my mother stop it.

i know twins that one is gay and one is straight.

but i don't know a set on gay twins.
