The difference in the number of these things possessed by the various castes of hymenopterans is believed to be linked to the evolution of eusociality. Distances along them are measured in centimorgans. Haplogroups based on mitochondria or one of these are the most frequently investigated ones. Telomerase lengthens the ends of these things. Having an abnormal number of these sub-cellular structures is called aneuploidy, and one example of that is Downs's syndrome. Staining and viewing them under a microscope is known as karyotyping. For 10 points, name these things that number forty-six in most human cells and contain densely-packed DNA.
