| Cephalic index and head shape are affected by geographical, gender, age and racial factors. This study carried out to determine cephalic index and head shape in 17-20 years old native Fars male in Gorgan, North of Iran. This descriptive study was done on 200 of 17-20 years old male native Fars by classic cephalometry in Gorgan, North of Iran. Mean and SD of cephalic index was 84.8 + 6.9. The head shape of 52% of individuals was hyperbrachycephalic, 25% brachycephalic, 21.5% mesocephalic and 1.5% dolichocephalic. Native Fars individuals showed typical hyperbrachycephalic. In comparing to other studies in world, we can conclude that the role of racial/ethnic factor in cephalic diameters |

| Abstract Polyploidy does not usually occur in germinal cells of mammals and other higher vertebrates. We describe a unique example of mosaic autotetraploidy in the meiosis of a human male. Although the original observations were made in the late 1960s, we did not publish them at that time, because we expected to detect further examples that could be described together. However, this did not occur and we have now decided to make the observations available to demonstrate that polyploidy in mammalian male meiosis can arise at a higher frequency than expected by random polyploidization of individual meiotic cells, by either DNA duplication or cell fusion prior to synapsis. This is the first description of a population of primary spermatocytes exhibiting... |
