G-banded karyotypes of four Egyptian species of order carnivora (Mammalia: Carnivora)

Abstract

The chromosomes of 4 carnivorous species were prepared and karyotyped from a bone marrow. 3 species from family Canidae including the Red Fox (Vulpes vulpes), the domestic dog (Canis familiaris) and a wild dog (Lycaon pictus) have a diploid chromosome numbers and fundamental numbers of, 2n=38 and FN=72, 2n=78 and FN=80, 2n=38 and FN=68, respectively while the diploid number and fundamental number of Domestic cat (Felis catus) which belongs to the family Felidae are 2n=38 and FN=72. Although the 3 species of V. vulpes, L. pictus and F. catus have the 2n=38, they are clearly different in their chromosome morphology and G-banded karyotypes.
