Chromatin bodies resembling sex chromatin are occasionally observed in tissues taken from males The statistical incidence of what appears to be sex chromatin in male cells normally ranges from about 2% in oral smears to as high as 20% in liver preparations. In fact, for an accurate determination of nuclear ser, a statistically significant number of cells must be examined and the percentage of cells having sex chromatin computed. For oral smears made from females, most investigators find that between 50% and 65% of the healthy cells demonstrate sex chromatin. Only normal-looking nuclei that stain evenly should be scored. Nuclei that are folded, have granulated nucleoplasm, oi demonstrate any sign of degeneration cannot be included in a critical study.1. Examine 50 squamous epithelial cells from a human female. How many exhibit sex chromatin?What percentage of these 50 cells reveal sex chromatin?2. What is the incidence of sex chromatin among 50 oral mucosal cells obtained from a human male?*3. Did you find any cells of the human female that appear to have more than one sex chromatin body?
