Plenty of Fish in the Sea but Only Two Kinds of Brains: Epigenetic Sex differences in Zebrafish Brain

Phenotypic differences between males and females of a species are referred to as sexual dimorphism. Sexual dimorphism manifests not only in morphological traits, but also in physiological and behavioural traits. In organisms that do not have sex chromosomes, males and females are both derived from a nearly identical genome. Such …

The Y chromosome has genome-wide influences over chromatin structure and gene regulation

In mammals, the Y chromosome is responsible for determining the male sex by initiating the development of male-specific gonad tissues. Hormones, produced and secreted by the sex organs, are vital for initiating and maintaining sexual dimorphisms. However, differences seen between the sexes are not solely derived from hormones. In fact, …
