  • Title: [Analysis of chromosome aberrations on the basis of synaptonemal complexes in the offspring of mice irradiated with gamma-rays].
    Author: Kalikinskaia EI, Bogdanov IuF, Kolomiets OL, Shevchenko VA.
    Journal: Genetika; 1986 Jul; 22(7):1119-26. PubMed ID: 3744039.
    Abstract:
    Electron-microscopic analysis of synaptonemal complexes (SC) spread on the surface of hypophase was carried out to study chromosome rearrangements in sterile and semisterile F1 offsprings of mice exposed to gamma-radiation at a dose of 5 Gy. Chromosome rearrangements were microscopically scored at diakinesis - metaphase I in the same animals. SC analysis at pachytene revealed chromosome rearrangements in 63% spermatocytes. Analysis of chromosomes at diakinesis - metaphase I in the same animals only revealed chromosome rearrangements in 32% cells. SC analysis permits detecting chromosome rearrangements undetectable at diakinesis - metaphase I.
