芬兰赫尔辛基大学的科学家研究发现,男性普遍比女性高与男女两性的X染色体数量有关。众所周知,女性有两条X染色体,男性则只有一条,而阻碍软骨发育的基因恰好位于X染色体,即女性阻碍软骨发育的基因强度是男性的两倍,一旦软骨停止生长,身高也就不再会增长。 A study by scientists at the University of Helsinki in Finland found that men are generally more likely to be female than men and women have more X chromosomes. It is well-known that women have two X chromosomes and one male. The genes that block the development of cartilage lie exactly on the X chromosome. That is, women have twice as many genes that block cartilage development as men. Once the cartilage stops growing, the height does not increase any longer .
