Is sexual dimorphism affected by the combined action of prenatal stress and sex ratio?

Abstract:

During embryonic development, offspring are exposed to hormones of both maternal and sibling origin. Maternal stress increases offspring exposure to corticosterone, and, in polytocous animals, the sex ratio or intrauterine position can influence the levels of androgens and estrogens experienced by the offspring. Such hormone exposure has the potential to influence many important morphological and behavioural aspects of offspring, in particular sexually dimorphic traits. Although well known in...
