The God of the Cult of the Mutant Monkey, Charles Darwin, born Feb. 12, explains that homosexuality can not be a trait that is "selected" by the gene pool.
If a trait 'gene' is beneficial in some way; it makes the progeny more likely to survive until reproduction or makes the progeny more successful in reproduction or the progeny bears more viable offspring itself, then the trait is selected by the gene pool and we see more individuals with that particular trait 'gene' over time.
If a trait makes the progeny less likely to survive to the age of reproduction, then having that trait makes the individuals with the trait less likely to pass it to the next generation. That type of trait is not selected by the gene pool and acquiring the mutation that makes one less likely to reproduce is the same kind of trait. If a gene causes the owner of the gene to become non-reproductive, the gene isn't passed to the progeny. We would see less and less of that trait.
Homosexuality will never be identified with any gene.
Finding it will DISPROVE Darwin's Theory of Evolution, and the discoverer will have to be awarded the Nobel Prize for Genetics.
