Heterochromatin polymorphism associated with 18S rDNA: a differential pathway among Hoplias malabaricus fish populations.

Cytogenetic and genome research - 1 Jan 2003

Vicari M R, Artoni R F, Bertollo L A C

Abstract excerpt

The distribution of constitutive heterochromatin has showed a relevant association with karyotypic evolution in several animal groups. In the present paper, a polymorphic condition for a heterochromatic segment overlapping a nucleolar organizer region in the fish species Hoplias malabaricus from the Iguaçu river, Southern Brazil, was analyzed. In accordance with previous studies, this population belongs to...
