So let's begin with anaphase one of meiosis one. So let's suppose we're at metaphase, and let's suppose that our cell consists of six chromosomes and not three chromosomes. So we take our gamethocide that consists of six chromosomes in human cells. We basically have 23 pairs of these tetris found at the center of our cell in metaphase. So let's suppose this is metaphase one of meiosis one, and we have the six chromosomes, and we have these three tetris. So each one of these pairs are homologous chromosomes that have undergone a genetic recombination process known as crossing over.
