So what we basically have to do is this relatively long punished square. So essentially we have eight different possibilities for the egg cell and a different possibilities for the sperm cell. So each one of these basically describes its own unique sperm cell that contains its own unique genotype. For example, this sperm cell contains all uppercase letters uppercase A, upper case B, uppercase C and this one contains uppercase A, upper case B and lowercase C and so forth. And these are individual unique cases. So just like in any punitive square.
