Five morphological parameters of sister chromatids, viz radius, length, centrometric index, volume and centromere width, were studied by electron microscopy, from 140 human number 1 chromosomes, and 122 human number 2 chromosomes. The degree of variation obtained ranged from 0.277 .+-. 0.003% and 0.286 .+-. 0.005% for the centromeric index of chromosomes 1 and 2, respectively, to 9.835 .+-. 0.933% and 13.472 .+-. 1.461% for centromere width.
