Cytogenetics in domestic animals

The Institute of Animal Breeding and Genetics has a cytogenetic department. We produce metaphase preparations and karyograms from various domestic animals (dogs, cats, horses, cattle and pigs). This can play a role in intersexual questions, for example. Chromosome abberation can sometimes be diagnosed in the Giemsa stain. For karyograms, the chromosomes are GTG-banded. A sex diagnosis in the horse can be clearly demonstrated by the C-banding. Within the scope of the sex diagnosis, we simultaneously perform a PCR to detect the SRY gene.
