T's harder to find one of the many genes involved in a polygenic trait vs. the only gene involved in a discrete trait."
<span>It is probably not very difficult to find ONE OF THE GENES involved in a polygenic trait (as this answer suggests), but it IS difficult to find ALL OF THE GENES involved in the trait. </span>
<span>This sounds like a high school Biology or first year university question - chances are they're testing your reading comprehension as much as your scientific knowledge.</span>
