Abstract
The phenotypes and gene frequencies of genetic markers in 8 blood group systems were studied in Japanese crossbred cats. The gene frequency was 0.051 for Ca, 0.949 for ca, 0.484 for TFF, 0.5133 for TFs, 0.279 for GCF, 0.721 for GCs, 0.945 for PGDA, 0.055 for PGDB, 0.544 for ESD1 and 0.456 for ESD2. Genetic polymorphism was not detected in the PGM, ACP and GLO systems.
