Abstract

An analysis of chiasma distribution in the nucleolar chromosomes of the grasshopperSphingonotus coerulans (L.) by means of silver staining revealed an underlying tendency for chiasmata not to be formed in the NORs. The possible meaning of this finding for the intact preservation of these regions through generations is discussed.
