further since the heterochromatin in m. booduga and m. dunni is expected to contain different repetitive dna sequences in addition to those homologous to m. musculus satellite dna , it is proposed that a change in the balance between two or more repetitive sequences in heterochromatin may be more crucial in its evolutionary consequences rather than a mere increase or decrease of a homogeneous repetitive sequence .
