从减数分裂前有丝分裂到减数分裂的各个阶段，染色体行为都会发生异常。
Abnormality of chromosome behavior occurs from premeiotic mitosis until various stages in meiosis.
几十年来，传统的理论认为X染色体与减数分裂以及男性不育无关，因为在男性减数分裂过程中X染色体被沉默掉了。
For decades, conventional wisdom stated that the X chromosome had little to do with meiosis or infertility because the X chromosome is silenced during male meiosis.
这意味着减数分裂中同源染色体不能配对，染色体间形成的交叉也会更少（例如，在减数分裂早期的重组位点）。
This means that homologous chromosomes failed to pair together during meiosis and chromosomes formed fewer crossovers, i. e. sites where they recombine, during the initial stages of meiosis.
