Sexual dimorphism is one of the most prevalent, and often the most extreme, examples of
phenotypic variation within species, and arises primarily from genomic variation that is …

The chicken continues to hold its position as a leading model organism within many areas of
research, as well as being a major source of protein for human consumption. The First …

The profound and pervasive differences in gene expression observed between males and
females, and the unique evolutionary properties of these genes in many species, have led to …

Bird sex chromosomes play a unique role in sex-determination, and affect the sexual
morphology and behavior of bird species. Core waterbirds, a major clade of birds, share the …

Detailed evaluations of genomic variation between sister species often reveal distinct
chromosomal regions of high relative differentiation (ie,“islands of differentiation” in FST), but …

Sexual dimorphism results from sex-biased gene expression, which evolves when selection
acts differently on males and females. While there is an intimate connection between sex …

How common is balancing selection, and what fraction of phenotypic variance is attributable
to balanced polymorphisms? Despite decades of research, answers to these questions …

Many genes are subject to contradictory selection pressures in males and females, and
balancing selection resulting from sexual conflict has the potential to substantially increase …

The attention given to heteromorphism and genetic degeneration of “classical sex
chromosomes”(Y chromosomes in XY systems, and the W in ZW systems that were studied …

In contrast to recessive conditions with biallelic inheritance, identification of dominant
(monoallelic) mutations for Mendelian disorders is more difficult, because of the abundance …
