So we have the mixing process take place and we form the following zygote. That eventually gives rise to this f one generation offspring. And so we have uppercase T, lowercase T. We basically have the following third case. And since the toll trade is dominant over that short trade, we have the fact that no matter which one of these possibilities we actually obtain, we always get the same exact result. Because uppercase t is domino or lowercase T, we get the fact that this will always resemble this parent and never this. Parent.
