There are plenty of things that caused by a combination of genes and environment. Heart disease and cancer are examples. You can look at someones family health history and see if they are prone to heart disease or certain cancers. But, people can influence whether or not they get those diseases by their habits. Some diet doctors use the phrase, genes load the gun, but diet pulls the trigger.
A person might be genetically coded to get wood around people of the same sex. Their environment obviously affects whether or not the suppress that desire or act on it, and whether or not to do it in the open. Environment might also impact expression of genes in some way and help determine who the guy gets wood for in the first place. Homosexual behavior is all over the animal kingdom, so there is really no arguing that it goes against evolution. Evolution created homosexuality over and over again in many types of animals. The only question is understanding the mechanism for it.
It seems like comments have numbers some days, but today they don't.
Are numbers important? I could put them back.

Actually, that does not seem to be true in humans. If a man were "genetically coded" to be gay, then his identical twin would also be gay. But 93% of the time, the identical twin is not gay.

No, exclusive homosexuality is exceptionally rare in the animal kingdom. Lots of animals, especially males, will fuck basically anything they can. Your dog will hump your leg. You just get the impression gayness is common among animals because the exceptions are promoted so strongly in the press as the highly-desired "evidence" that gayness is in absolutely no way a choice.

There's a difference between being excited by someone of the same sex and admitting it. There's also a difference between what your genes make likely and what gets expressed. So your test whereby you expect 100% match is the wrong test. I'll ask you this. Is cancer caused by genes? Do some people get large muscles because of genes? The answer to both questions is mixed. Genes certainly help some people develop big muscles, but two identical twins separated at birth will not have the exact same size muscles. One might get cancer at 40 and the other might not develop it in his lifetime. If you your test for something being caused by genes is 100% equal results, then you will find that nothing is caused by genes.
If people find that the chance of being gay is affected by genes, then it is partially out of their control and not determined completely by nurture. Same goes for disease.

@"P N Dr Lo R" The comment numbers are back now.
I guess they do add some useful info.
