“…Discussion The detection of se,mal dimorphism of nuclei in various ceII types of the lion agrees with observations that have been made previously in other members of the order Carnivora (5,10,12,16). I t is generally assumed now, on good evidence (21), that the sex chromatin represents heterochromatic parts of one of the X-chromosomes of the female sex chromosome complex.…”

“…A characteristic chromatin pattern for males and females is present in most cell types of primates (17,24) and carnivores (5,10,12,16). In the orders Artiodactyla (14,18,20,23,26) and Perissodactyla (12a) sexual dimorphism is recognizable in neuronal nuclei, but in nearly all other cell types, the general nuclear chromatin is so coarse that sex differences are not usually recognizable.…”

A sex difference is present in the structure of interphase nuclei of somatic cells in a variety of tissues of the lion. In the female, but not in the male, there is a special mass of chromatin, the sex chromatin, which stands out from the general particulate chromatin. In neurons the sex chromatin is usually located adjacent to the nucleolus, but in other cell types it nearly always lies against the inner surface of the nuclear membrane. The sex chromatin has the cytochemical properties of desoxypentose nucleic acid and is probably derived from heterochromatic regions of one of the X-chromosomes of the female's sex chromosome complex. A mass similar to the sex chromatin of females is rarely encountered in nuclei of males. The sexual dimorphism present in interphase nuclei of the lion is similar to that described previously in other carnivores and in primates.
