So we have uppercase T. So we have uppercase dark purple tea and uppercase light purple tea. Now in this case we have a short plant that is true breeding which means both of these genes are lowercase T and that means they're short, they're recessive. And so let's suppose we have a red color and we have the orange color for the second lowercase T. Now this is called the law of Dominance. What he proposed next was the principle of segregation, also became known as the law of segregation or Mendel's law of Segregation. Now, what he argued was that whenever the gametes are formed before we actually have the mating process take place, the two genes that code for that same trait. In this case, the height behave like particles and actually separate.
