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. We basically have to combine the Xcel with the sperm cell and we basically combine our genotype. So we have uppercase A, uppercase A, upper case B, uppercase B, and uppercase C, uppercase C to form the zygote. So uppercase A, uppercase A, upper case B, uppercase B, uppercase C, uppercase C, and we continue the process with all these different types of combinations.
