Like red hair? Red hair is being bred out of humanity just over the last two thousand years. At one point half of Europe had red hair, and now it's vanishing.
For a recessive trait to appear in an offspring, both parents would have to have had a copy of the trait. That happens less and less with successive generations, until eventually it vanishes.
Clearly, being gay is mostly learned behavior, not hereditary. If your father is gay......... is he your father? He could be, but homosexual behavior is learned, not hereditary
