A SEX dimorphism of interphase chick nuclei has been reported by Kosin and Ishizaki [2, 41. Ashley and The&s [l 1, on the other hand, were unable to find an interphase nuclear dimorphism in chickens, chromatin masses being common in the nuclei of both sexes. Ohno, Kaplan, and Kinosita [9] have reported a sex dimorphism for prophase nuclei. Since sex chromatin is usually more readily demonstrable in cultured cells than in tissue sections [5, 61, and since such a marker would be useful in chicken cell cultures, a tissue culture study was undertaken. Studies were also done with tissue sections using conventional techniques. |
