Disruption of the antipairing pattern occurs in cancer cells. However, little is known about how this spatial organization of chromosomes is established or maintained. WebAn egg is a haploid cell, which means that it contais only one set of chromosomes, unlike the diploid cells found in most of our body that contain two sets of chromosomes.
