Chromosome identification of the rusty-spotted cat (Felis rubiginosa): one more down and four to go.
The chromosomes of the rusty-spotted cat, Felis rubiginosa, of Sri Lanka (Ceylon) were analyzed. Although the 38-chromosome complement of F rubiginosa closely resembles that of several other species, it seems to be unique with only minor variations in the D and F chromosomes. This reduces, from 5 to 4, the number of the 37 recognized world feline species not yet cytogenetically studied. Despite great differences in size and distribution, the feline species of the world are one of the most homogenous families of mammals, with only subtle chromosomal differences separating most species. By comparative cytogenetic analyses, it is becoming possible to map the probable evolutionary pathway of the world's cats.
