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.
对来自五名正常男性的每个人类染色体，在早中期和中期比较了其相对长度和着丝粒指数。在这两个参数上，早中期和中期染色体之间几乎没有差异。7号染色体在早中期和中期的着丝粒指数有显著差异，但相对长度没有差异。这是由于早中期和中期之间7p和7q的相对长度存在显著差异；随着从早中期发展到中期，7p相对变得不那么浓缩，而7q相对变得更浓缩。对于1号染色体，在早中期和中期，短臂都明显长于长臂，这一发现强调了该染色体在灵长类动物中的结构相似性。
