So to see what we mean, let's take a look at the following diagram. So this is the tall true breeding plant. And what that means is it contains two genes that are both essentially tall. 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.
