Sex-specific selection and intraspecific variation in sexual size dimorphism.
Sexual size dimorphism (SSD) is thought to evolve due to sex differences in selection on body size, but it is largely unknown whether intraspecific variation in SSD reflects differences in sex-specific selection among populations. We addressed this question by comparing viability selection between two island populations of the brown anole lizard (Anolis sagrei) that differ in the magnitude of m...
متن کاملSex-linked inheritance, genetic correlations and sexual dimorphism in three melanin-based colour traits in the barn owl.
Theory states that genes on the sex chromosomes have stronger effects on sexual dimorphism than genes on the autosomes. Although empirical data are not necessarily consistent with this theory, this situation may prevail because the relative role of sex-linked and autosomally inherited genes on sexual dimorphism has rarely been evaluated. We estimated the quantitative genetics of three sexually ...
متن کاملSexual dimorphism in airway responsiveness to sex hormones in rabbits.
TO THE EDITOR: Recently, Massaro and Massaro (4) demonstrated a sexual dimorphism of alveolar size in male and female adult rats and mice and that estrogen receptor (ER)and ERare required for this sexual dimorphism. Our group recently showed that a similar phenomenon of sexual dimorphism presents in airway responsiveness to sex hormones in rabbits. We studied the direct effect of sex hormones (...
متن کاملSexual dimorphism in glioma glycolysis underlies sex differences in survival.
The molecular bases for sex differences in cancer remain undefined and how to incorporate them into risk stratification remains undetermined. Given sex differences in metabolism and the inverse correlation between fluorodeoxyglucose (FDG) uptake and survival, we hypothesized that glycolytic phenotyping would improve glioma subtyping. Using retrospectively acquired lower-grade glioma (LGG) trans...
متن کاملSexual growth dimorphism affects birth sex ratio in house mice.
We present the first empirical evidence that mammalian sex-ratio deviations result from variation in adult-weight sexual dimorphism via correlated effects on blastocyst development. Two selection lines of mice exhibiting high and low sexual dimorphism in adult weight showed correlated sexual weight differences at birth and at weaning, caused by relatively decelerated growth of males in the low ...
