Distribution of constitutive heterochromatin (C-bands) in the somatic chromosomes of an Indian bird,Chrysomma sinense (Gmelin)

Summary The localization of constitutive heterochromatin has been studied in a passerine bird,Chrysomma sinense (2n=±70). In all the 7 pairs of macrochromosomes pericentric heterochromatin has been observed as usual except in pairs Nos 2 and 4, in which both pericentric and non-centromeric heterochromatin have been recorded.The authors are grateful to Prof. B.
