So if we zoom in on this picture, we basically get the following diagram. So this is a homologous pair of chromosomes, and this is also a homologous pair of chromosomes. But within each one of these pairs, we now have identical cystochromatids. So this chromosome is identical to this one, and this one is identical to this one. But these two are homologous with respect to one another. So remember, what we mean by homologous is they carry similar genes.
