So let's say that this codes for some type of trait. Let's suppose it's the height, and this also must code for that same type of trait for the height. But that doesn't mean that these must code for the same exact type of protein. The proteins can actually differ. In fact, this gene can code for a toll plant, but this gene can code for a short plant. And in that particular case, because the toll trade is dominant over the short trade, this will actually express the trade.
