The zebra finch is an important model organism in several fields, with unique relevance to
human neuroscience,. Like other songbirds, the zebra finch communicates through learned …

Differences between males and females in the optimal phenotype that is favoured by
selection can be resolved by the evolution of differential gene expression in the two sexes …

The “four core genotypes”(FCG) model comprises mice in which sex chromosome
complement (XX vs. XY) is unrelated to the animal's gonadal sex. The four genotypes are XX …

Females and males often differ extensively in their physical traits. This sexual dimorphism is
largely caused by differences in gene expression. Recent advances in genomics, such as …

Contrary to classic theory prediction, sex-chromosome homomorphy is prevalent in the
animal kingdom but it is unclear how ancient homomorphic sex chromosomes avoid …

Three principal types of chromosomal sex determination are found in nature: male
heterogamety (XY systems, as in mammals), female heterogamety (ZW systems, as in birds) …
