This work explores recent advances in the study of vertebrate sex chromosomes achieved using genomic analyses using whole genome sequences from a variety of organisms.
Abstract
Sex chromosomes have evolved multiple times in many taxa. The recent explosion in the availability of whole genome sequences from a variety of organisms makes it possible to investigate sex chromosome evolution within and across genomes. Comparative genomic studies have shown that quite distant species may share fundamental properties of sex chromosome evolution, while very similar species can evolve unique sex chromosome systems. Furthermore, within-species genomic analyses can illuminate chromosome-wide sequence and expression polymorphisms. Here, we explore recent advances in the study of vertebrate sex chromosomes achieved using genomic analyses.

Origins and functional evolution of Y chromosomes across mammals

TL;DR: Although some genes evolved novel functions through spatial/temporal expression shifts, most Y genes probably endured, at least initially, because of dosage constraints, and show notable conservation of proto-sex chromosome expression patterns.

Are all sex chromosomes created equal

TL;DR: This work elucidate how the differences among these systems can be exploited to gain insights about general evolutionary processes, genome structure, and gene expression and suggest directions for research that will greatly increase general understanding of the forces driving sex-chromosome evolution in diverse organisms.

Polygenic sex determination system in zebrafish

TL;DR: Zebrafish sex is genetically determined with limited, secondary influences from the environment, and it is proposed that the zebrafish has a polygenic sex determination system.

Recombination in the threespine stickleback genome--patterns and consequences.

TL;DR: It is demonstrated that recombination rate correlates with both the magnitude of allele frequency shifts between populations and levels of genetic diversity within populations and deserves wider recognition in marker‐based genomic analyses.

Chromosomal redistribution of male-biased genes in mammalian evolution with two bursts of gene gain on the X chromosome.

TL;DR: Two bursts of gene gains occurred on the mammalian X chromosome contribute to an age-dependent chromosomal distribution of male-biased genes.

Genome sequence of the Brown Norway rat yields insights into mammalian evolution

Richard A. Gibbs, +242 more
- 01 Apr 2004 - 
TL;DR: This first comprehensive analysis of the genome sequence of the Brown Norway (BN) rat strain is reported, which is the third complete mammalian genome to be deciphered, and three-way comparisons with the human and mouse genomes resolve details of mammalian evolution.
