    The variability of patterns of sexual dimorphism in the hominoid skull (1990)
    Springer
    Cellular and molecular life sciences 46 (1990), S. 670-672

    Notes: Summary Univariate and multivariate statistical analyses are applied to a number of cranial dimensions and angles from living hominoids in order to investigate the patterns of sexual dimorphism in these groups. Clear differences in patterns of cranial sexual dimorphisms are demonstrated not only between genera but also within a single species (Homo). These differences overlay the common finding of a sexual size difference in all groups. The results imply that caution is required in using the sexual dimorphisms of living hominoids as models for those anticipated in fossils.

    Multinucleate spermatids in the mouse (1974)
    Springer
    Cell & tissue research 150 (1974), S. 323-329 
    Details
    ISSN: 1432-0878
    Keywords: Spermiogenesis ; Mouse ; Multinucleate spermatids ; Electron microscopy
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary Electron microscope studies of the testes of five inbred and three outbred mouse strains show that the usual frequency of multinucleate spermatids is between one and two percent. In C57 BL/6J and A/Gr however it is higher (4–5%). The frequency of the shared acrosome condition, which would lead to the formation of an abnormal sperm, is 1.3 per thousand.
