title: Cytogenetic research techniques in humans and laboratory animals that can be applied most profitably to livestock.
abstract: The usefulness of various chromosome banding techniques, i.e., Q, C, G, R, Ag-NOR, and SCE, which are currently in use in many clinical cytogenetics labortories are discussed. Since C-banding revealed the location of constitutive heterochromatin, it must be applied in conjunction with Q, G, or R-banding techniques. For the longitudinal differentiation of mammalian chromosomes one can use either the G-banding or the Q-banding and, if possible, R-banding technique. The results of such studies should not only contribute to our understanding of cytogenetics of domestic animals but also assist breeding programs and improvement of livestock.
