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? Well, basically, we can have this cell combined with this cell to form the following cell that contains upper case T that came from parent one and lower case T that came from parent one. Or we can also have this T combined with this T to form this cell, this T combined with this T to form this cell and this T to combine with this T to form this cell. So we have a total of four different potential possibilities of the offspring.
