So we have lowercase, lowercase T. And then we have gamete formation. We have these X cells that are formed. And so we have lowercase T, lowercase T. Now, we know when fertilization takes place to form the offspring, to form that zygote, the two cells actually fuse to basically form a single cell, a zygote that contains a diploid number of organisms. So we have a haploid number, a haploid number. They fuse to form a diploid, and these chromosomes combine. Now, the question is, what exactly are the possibilities of the offspring?
