Actually, there is no big rush to find a “gay gene” because the scientific community understands homosexuality is normal variance within the animal kingdom.
Its also true that in the animal kingdom there are few commitments amongst them.
And many wander from place to place and the males of most species do not ever meet their ‘offspring’ nor nurtur them.
And comparing the animal kingdom, there aren’t ‘weddings’ and permanent homes.
Every creature sleeps around and none of them have the aptitude or the intelligence to build houses, create some sort of commerce, rely on other species [except to eat them] and so forth.
So why does the human community compare itself to the animal kingdom time and again.
FWIW - i havent yet heard of animals doing any studies.
When they can compare to our intelligence and skills to build elobrate homes, vehicles, movies, and other technologies such as cell phones and internet…then we’re talking.
But since animals are different from mankind in respect to worshipping God, intellectually understanding what is or is not moral - means comparisons are moot point.
How many humans have intercourse while walking down the street in front of others and keep walking with another hanging on ?
Or how about leaving a lame child on the side to be eaten by predators because they need a hospital?
Sorry - humans really shouldnt compare themselves to the rest of the animal kingdom since we are advanced in many ways.
Even if a ‘gene’ existed - it would be morally perverse.
AND animals do not need to think things thru - but on the off chance one is ‘gay’ or mutated, their species discontinue. [Their own genetics]
Animals usually avoid same sex because their genetics wouldnt pass on any other way.
