The evidence in support of two types of alternate disjunction in translocation heterozygotes from the German cockroach, Blattella germanica (L.), is reviewed. When unique cytomorphological features occur in the translocation figure, the two types of alternate disjunction are identifiable regardless of the angle of observation. Photographs supporting this contention are presented for alternate-1 and alternate-2 disjunction in T(7;12)/7;12 . Other evidence in support of the existence of alternate-2 disjunction is also presented.
支持德国蟑螂（Blattella germanica（L.））易位杂合体中两种类型的交替分离的证据进行了回顾。当易位图形中出现独特的细胞形态特征时，无论观察角度如何，都可以识别出这两种类型的交替分离。为 T（7；12）/7；12 中的交替-1 和交替-2 分离提供了支持这一论点的照片。还提出了其他支持存在交替-2 分离的证据。
