 Hi, team. So in today's lecture, we're going to talk about inheritance patterns or problems that don't explicitly follow Mendelian rules. Some of them actually are following logical inheritance patterns and others are just, they just are resulting in different phenotypic classes for whatever reason and others actually are influencing the classes such that influencing the DNA such that it becomes extremely messy. This is a cool lecture because it sheds light on how incredibly complicated discussions of genetics and heredity actually are. It's really easy when we sit down with our little pen and squares and our little letters to be like, oh man, we've got this. We can figure out anything that we want to in terms of what our babies are going to look like. But the fact is that genetics is extremely complicated. There are many, many factors and this nine-part lecture today is going to talk about just a handful of those factors that can complicate things. So we're going to start out by looking at, we're going to basically move from easier to not as much easier and we'll see how we feel at the end of this thing. So let's talk about incomplete dominance first.
