众所周知,人类的细胞中有23对染色体。其中包括22对常染色体和1对决定性别的性染色体,男女的性染色体又有所不同,男性是XY,而女性是XX。但你是否知道,男性专属的Y染色体一直在消亡并缩小?数百万年前Y染色体上有1500个基因,现在却只剩下40多个,这意味着,如果Y染色体继续枯竭,在不久的将来,男性可能会失去它。近年来男弱女强的观点盛行,加上人工精子、体外子宫等科学的新探索,在未来人类的
It is well known that there are 23 pairs of chromosomes in human cells. These include 22 pairs of autosomes and one pair of sex-determining sex chromosomes. The sex chromosomes of men and women are different. Men are XY, and women are XX. But did you know that the male-specific Y chromosomes have been extinct and have been shrinking? 1500,000 genes are present on the Y chromosome millions of years ago, leaving only about 40, which means that if the Y chromosome continues to dry up, In the future, men may lose it. In recent years, the prevalence of weak men and women, coupled with artificial sperm, uterus and other new in vitro exploration of science in the future of human
