Abstract
|
|
|
|
None of the numerous published canis idiogram and karyotypes has yet been generally accepted as a standard one because the dog has 76 acrocentric autosomes of similar size and shape. The karyotypes of DongGyeongi dog were analysed by conventional trypsin/Giemsa staining (GTG-banding techniques), and were compared with one another. There were no variations in karyotypes which were analysed by conventional GTG-banding techniques, but differences were observed in G-banding patterns with sapsaree (or canis familiaris strains). It is not clear that these disagreements in G-banding patterns between strains of dog were caused by chromosome polymorphism or a difference in interpretation.
