摘要
由一条染色体变成两条染色体的过程称为染色体的复制.减数第一次分裂(简称减1)的间期只存在DNA的复制以及随后的染色单体的复制,不存在染色体的复制.减数第二次分裂(简称减2)的中期,随着一条染色体的着丝点发生分裂完成染色体的复制,由一条染色体变成两条染色体.
The process that item chromosome changed into two chromosome is known as the chromsome replcation. The interphase of first division in Meiosis（MI） exist only as DNA replcation and follow on the chromatid replcation, but does not exist as chromosome replcation. The metaphase of second division in Meiosis（ M2）, the finishing chromsome replcation item chromsome to be changed into two, following the cenromeric division in item chromosome.
