The centromere index and relative length of human high-resolution G-banded chromosomes. 1986

D L Van Dyke, and M J Worsham, and L J Fisher, and L Weiss

The relative length and centromere index were compared in prometaphase and midmetaphase for each human chromosome from five normal men. There were very few differences between prometaphase and midmetaphase chromosomes in these two parameters. Chromosome 7 had a significantly different centromere index between prometaphase and midmetaphase, but no difference in relative length. This was accounted for by significant differences in the relative length of both 7p and 7q between prometaphase and midmetaphase; 7p became relatively less condensed and 7q relatively more condensed with progression from prometaphase to midmetaphase. For chromosome 1, the short arm was significantly longer than the long arm in both prometaphase and midmetaphase, a finding that underscores the structural similarity of this chromosome among the hominids.
