Abstract
Meiosis in P. notatus shows certain well defined abnormalities which arise from a precocity in the movements of the centers. This upsets the normal coordination of the mitotic processes, and results in an asymmetrical mitotic figure in the 1st division, abnormal division of the chromosomes in the 2d, and the production of multinucleate spermatids. Chromatin bridges that characterize all 2d divisions arise from a failure of the chromatids to disjoin and are not due to inversions.This publication has 1 reference indexed in Scilit:
