本文报道了一例rob(13;14)携带者的57组精子染色体观察分析结果,正常与平衡染色体组率分别为52.6％和35.1％,不平衡染色体组率为12.3％。这三个比率的分布与理论比例有差异,作者认为差异原因有两种可能性解释。
In this paper, we observed the chromosomal analysis of 57 spermatozoa in a case of rob (13; 14) carriers. The rates of normal and balanced chromosomes were 52.6% and 35.1% respectively, and the unbalanced chromosomes were 12.3%. The distribution of these three ratios is different from the theoretical ratio. The author thinks there are two possible reasons for the difference.
