Chromatin Elimination in Glaucoma pyriformis (Ehrb.)

Abstract

CHROMATIN elimination at the end of each division from the macronucleus was reported by Kidder1 in Concophthirius mytili. Later, Kidder and Diller2 observed post-divisional chromatin elimination in Urocentrum turbo, Colpidium colpoda, Colpidium campylum and Glaucoma scintillans. Again, in 1936, Diller3 recorded a peculiar type of chromatin elimination in Paramecium aurelia which he termed ‘hemixis’. Seshachar4 confirmed this in three species of Epistylis. The present note embodies certain interesting features concerning the behaviour of the macronucleus during binary fission in Glaucoma pyriformis.
