Cytogenetic studies in a canine mammary tumor.
In a 9-year-old female dog (Basset Artesian Normand) with a mammary adenocarcinoma, cytogenetic evaluation of tumor cells showed a chromosome number of 76 in most metaphases (95%). The following abnormalities were found: symmetric metacentric chromosomes 1 and 6, centric fusion 3/38, a marker X-chromosome (Xmar) and a biarmed small marker chromosome (mar). In the remaining metaphases (5%) there were additional biarmed marker chromosomes present.
