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).
