The sex chromosomes of Microtus chrotorrhinus are unusually large compared to those of other mammals, comprising about 20% of the karyotype and containing substantial amounts of constitutive heterochromatin. Previous studies have described two highly repeated DNA families (MSAT-160 and MSAT-2570) that localize to this heterochromatin (Modi, 1992, 1993c). The present report describes a third satellite DNA family (termed MSAT-21) in M. chrotorrhinus that is also located in the sex heterochromatin… CONTINUE READING
