A correlation between Y chromosome length and stature was statistically analyzed in a normal male population of 142 Japanese students with a mean age of 24.0 years. Evidence was obtained that increased length of the heterochromatic band Yq12 may be associated with increased height: The correlation coefficient between band Yq12 length and height was 0.17, statistically significant at the 5% level. And, taller males had longer Y chromosomes, in which the mean length of band Yq12 was significantly longer than that of shorter males. No correlation was seen between length of the euchromatic band Yq11 and stature. The present study reveals a possible effect of Yq heterochromatin on the development of body height in man.
对142名平均年龄为24.0岁的日本男学生正常男性群体进行了Y染色体长度与身高之间相关性的统计分析。有证据表明，异染色质带Yq12长度增加可能与身高增加有关：Yq12带长度与身高之间的相关系数为0.17，在5%水平上具有统计学意义。而且，较高的男性Y染色体较长，其中Yq12带的平均长度明显长于较矮男性的Yq12带平均长度。常染色质带Yq11的长度与身高之间未发现相关性。本研究揭示了Yq异染色质对人类身高发育可能产生的影响。
