Evaluation of chromosomal changes in gonads and their potential effect on boar fertility
Języki publikacji
Abstrakty
The aim of this study was to analyze the reasons for abnormal meiosis in an infertile boar, the carrier of a reciprocal translocation, rcp(9;14)(q14;q23). The study was based on observations of synaptonemal complexes, the protein structures occurring during pairing of chromosomes. The specific morphology of the X-Y bivalent at different stages of pairing made it possible to identify several substages of prophase I: late zygotene (Z/P), early pachytene (P1), mid pachytene (P2) and late pachytene. A total of 448 primary spermatocytes were evaluated. In all cells the authors observed the presence of a structure characteristic of reciprocal translocations . a tetravalent formed from chromosomes created as a result of an exchange of chromatids between autosome pairs 9 and 14 and their homologues.
