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. For example, let's suppose we look at this one. So for this particular zygote, we combine an excel that contains all lowercase letters, a sperm cell that contains all uppercase letters, and we form three uppercase letters and three lowercase letters. So uppercase A, lowercase A, upper case B, lowercase B, and uppercase C, lowercase C, and we do this with every single one of these squares.
