美国宾夕法尼亚州立大学的2位科学家在性染色体进化变异机制的研究上取得进展。研究发现,Y染色体比X染色体的演化速率快得多,这将导致Y染色体上的基因急剧丢失,如此,Y染色体将会完全消失,人类的传宗接代将受威胁。生物学副教授卡特雷纳.玛克瓦(Kateryna Makova)和美国国家科学?
Two scientists at Penn State University made progress in the study of mechanisms of evolutionary variation in sex chromosomes. The study found that the Y chromosome evolves much more rapidly than the X chromosome, which results in a drastic loss of the gene on the Y chromosome so that the Y chromosome will completely disappear and the human transmission will be threatened.
