Abstract
This article is a second part of the themed issue "Aberrant cytogenetic and reproductive patterns in the evolution of Paraneoptera insects", prepared by the Russian-Bulgarian research team. Here, analysis of aberrations related to the egg development is provided based on literature data and the author's own investigations. Evolutionary aspects of ovoviviparity/viviparity are also briefly discussed. Material and methods, terminology and nomenclature of taxonomic names are listed in the first paper of the issue (Gavrilov-Zimin et al. 2021).
本文是俄罗斯-保加利亚研究小组编写的 "副翅目昆虫进化过程中的异常细胞遗传和繁殖模式 "专题的第二部分。在此，根据文献数据和作者自己的调查，对与卵发育有关的畸变进行了分析。此外，还简要讨论了卵胎生/胎生的进化问题。材料与方法、术语和分类名称的命名方法已在本期第一篇论文（Gavrilov-Zimin et al.）
