Previously undocumented regional variability in crab‐eating macaque skull sexual dimorphism and its implications for biological and morphometric studies

The Anatomical Record, EarlyView.
Abstract In a large sample of adult crab‐eating macaques, we quantified sexual dimorphism in size, shape, and covariance across the whole skull and among anatomical regions of the cranium and mandible. All regions showed significant mean sex differences, but the magnitude of size and shape dimorphism varied substantially.

Chromosome‐aberration tests

Food Additives & Contaminants, 1984
Three points related to the subject of chromosome-aberration tests and carcinogenicity screening are dealt with in this paper. First, the relation between chromosome rearrangements and oncogenesis is briefly discussed, to stress the relevance of cytogenetic assays to assessment of the carcinogenic potential of drugs.

X Chromosome Aberrations

1999
Abstract In this chapter we consider gonadal maldevelopment caused by X-chromosome aberrations. As in Chapter 5, “gonadal maldevelopment” is defined broadly so that it includes defective spermatogenesis due to an extra X chromosome in XXY males and gonadal dysgenesis due to accelerated oocyte attrition in XO females. These two conditions,
