But it was being inhibited, it wasn't actually being expressed. So because of that, what he proposed was that each one of these plants contain two hereditary factors that code for that given trait. In this case for that given height. And nowadays we know that these two hereditary factors are simply the genes found on homologous chromosomes and we'll see exactly what that means in just a moment. So basically he argued that because this tall f one generation offspring contains that short trade but the short trade is not being expressed. That means the tall trade is actually dominant over that short trade which is said to be recessive.
