Hello Parents and Students,
This week we have been learning about characteristics. How are parents pass down our blond hair and blues eyes, or our big feet and our height. Here is an activity that will help us with this.
The Punnett square is a chart, used by geneticists, to help determine the chances of an offspring receiving a particular characteristic. The Punnett square will not tell you how many offspring will develop, or the order in which they will be born. It will tell you what kind of genotypes the children will have. Remember genotypes are consisted of alleles. An allele is represented by a single letter (e.g. A or a).
Try your skills with determining eye color. You will get to pick the fathers and mother eye color from a drop down menu and then find out what color eyes there child will have. Find to dog's inheriting deafness from there parents. In this activity you get to try and get the genotype right. It will tell you if you're right or not. At the top there is another eye color challenge it you choose to try. Try and use a blank Punnett square to try many different genes (it is based on chinchilla's but works for any genotype)! Test your knowledge and make up you own genotypes. Type in what you want and see what comes out. The more you practice the Punnett Square the better off you will be for the test!!
