Frequency of chromosomal aberrations in two inbred mouse layers (Mus musculus)

Abstract

Frequency of chromosomal aberrations in two inbred mouse layers (Mus musculus)?. BALB and C57 mice inbred strains were analysed by means of ?in vivo? cytogenetic techniques in order to determins the frequency of chromosoma aberrations not induced by any clastogen. These findings are analysed taking into account that chromosome aberrations play a fundamental rols in the evolution of karyotypes. The knowledge of the phenomena involved in the production of spontaneous macromutations could contribute to the understanding of several cytotaxonomic problems.
