Abstract

In many mammals, especially rodents, centric fusions of acrocentric chromosomes constituted the most common mechanism of chromosome structural changes during the course of karyotypic evolution. The present study is an attempt to present here a detailed description of early meiotic stages (i.e. pachytene diplotene and diakinetic configurations) with an emphasis on the identification of distinctive features of the elongated chromosome (chromomeric) sequences. This together with a prometaphase idiogram could provide a schematic representation of Syrian hamster meiotic chromosomes, especially of X and Y chromosome behavioral patterns during the early meiosis.
