So let's take a look at this tetrid here. So this chromatid and this chromatid are basically the same chromatid that we began with in this diagram before the S phase actually took place. So these are the two original homologous chromosomes where one came from the mother and one came from the father. And notice what happens in the process of anaphase. So our chromosome that came from the father is separated from the chromosome that came from the mother. And this means that our genes that are homologous, that code for the same type of traits, are separated during the process of anaphase.
