Hi, I'm Robin Higgins and this is everyday uses of biology. Okay, so biology is a study of life. And so obviously we are alive we are using biology right now by being alive. And some common ways that we use it in real life are gardening. So plants are also alive needing their proper nutrients. And they also need to have the correct conditions. They need sun. You can't put them in freezing temperatures unless they are very specific plants. So every time you are thinking about different conditions that a living creature would need you are thinking about biology. And so this isn't limited just to plants but yourself and your own health. So what your diet is is biology. And how you exercise. And of course we have other fields because we are humans and so there's enough information that we care about diet and exercise to have our own fields. But they are all under the umbrella characterization of biology. Now if we want to get really nitty gritty with actual stuff we learn in biology class we can go into some basic gene expression stuff. Lets say you have a parent that has brown eyes. One parent has brown eyes and the other parent has blue eyes. From the way that genes work is that you have two little slots and it'll be filled with the genes from your parents. And so if you ave a big R this is dominant. If you have a little r this is recessive. So the way that biology works is that between brown and blue, brown is dominant. So it's upper case. And lower case is recessive so it's blue in lower case. And so if you have blue eyes you have to have both recessive genes because if you have one Upper case or brown gene it's basically like a trump card. So you won't be able to have those blue eyes anymore. So if these people have a kid there is, the kid is going to get one from each of them. And it's definitely going to get one of these little r's cause that's all this parent has to offer. And then it's going to get either this upper case brown gene or a lower case blue gene and it's completely up to luck. So lets say this time it gets this lower case and that means that kids will have blue eyes. But lets say they have another kid a few years later. Again they can only get a lower case from this parent. And lets say this time they get the upper case R so they are going to get brown genes and they are going to have brown eyes. This is a little bit more into the science of biology but it's one way that you can use basic biology to predict the eye color of you and your friend's children. Alright I'm Robin Higgins and this is everyday applications for biology.
