The peculiar cytology and unique evolution of sex chromosomes raise many fundamental questions. Why and how sex chromosomes evolved has been debated over a century since H.J. Muller suggested that sex chromosome pairs evolved ultimately from a pair of autosomes. This theory was adapted to explain variations in the snake ZW chromosome pair and later the mammal XY. S. Ohno pointed out similarities between the mammal X and the bird/reptile Z chromosomes forty years ago, but his speculation that… Expand
A new look at the evolution of avian sex chromosomes
TLDR
Recent research into avian sex chromosomes is examined and an alternative to independent evolution of bird and mammal chromosomes is suggested, in which an XY system took over directly from an ancestral ZW system. Expand
Genomics of expanded avian sex chromosomes shows that certain chromosomes are predisposed towards sex-linkage in vertebrates
TLDR
Comparative genomics of birds where multiple chromosomes appear to have formed neo-sex chromosomes shows that there is extensive homology to sex chromosomes in other vertebrate lineages and finds that the fourth chromosome, chromosome 3, was significantly enriched for genes with predicted sex-specific functions. Expand
Monotreme sex chromosomes--implications for the evolution of amniote sex chromosomes.
TLDR
The recent completion of the platypus genome sequence has completely changed the authors' understanding of when the therian mammal X and Y chromosomes first arose and has also revealed the unexpected insight that sex determination of the amniote ancestor might have been controlled by a bird-like ZW system. Expand
Are some chromosomes particularly good at sex? Insights from amniotes
TLDR
It is argued that gene content can predispose some chromosomes to a specialized role in sex determination, and therefore well conserved but independently evolved sex chromosome systems have arisen in mammals and lizards. Expand
The evolution of sex determination associated with a chromosomal inversion
TLDR
It is suggested that a new male-determining gene evolved in the inversion in response to selection against impaired male fertility in a hybridized population. Expand
A Syntenic Region Conserved from Fish to Mammalian X Chromosome
TLDR
A syntenic segment within this region that is well conserved in several teleosts was shown to be present in mammalian X chromosomes, suggesting a common ancestral origin of vertebrate sex chromosomes. Expand
Y Fuse? Sex Chromosome Fusions in Fishes and Reptiles
TLDR
This work estimates the rate at which fusions between sex chromosomes and autosomes become established across the phylogenies of both fishes and squamate reptiles and identifies other combinations of evolutionary forces that might in principle account for the data although they appear less likely. Expand
Dynamics of vertebrate sex chromosome evolution: from equal size to giants and dwarfs
TLDR
It can be concluded that, due to accumulation of repetitive DNA and transposons, the Y and W chromosomes can increase in size during the initial phase of their differentiation. Expand
Mammalian sex--Origin and evolution of the Y chromosome and SRY.
TLDR
The organization and evolution of the sex chromosomes across a broad range of mammals is discussed, and how the Y chromosome, and SRY, evolved is speculated on. Expand
Origin of Amniote Sex Chromosomes: An Ancestral Super-Sex Chromosome, or Common Requirements?
TLDR
Comparative gene mapping and whole genome sequencing have now turned up other surprising relationships; different regions of the amniote genome that have become sex determining in some taxa seem to share synteny, or share sequence, in others. Expand

Evolution of the avian sex chromosomes from an ancestral pair of autosomes.
TLDR
It is shown that the two genes, ATP5A1 and CHD1, so far assigned to the female-specific W chromosome of birds both exist in a very closely related copy on the Z chromosome but are not pseudoautosomal, indicating a common ancestry of the two sex chromosomes, consistent with the evolution from a pair of autosomes. Expand
In the platypus a meiotic chain of ten sex chromosomes shares genes with the bird Z and mammal X chromosomes
TLDR
It is demonstrated that platypus has five male-specific chromosomes and five chromosomes present in one copy in males and two copies in females that form a multivalent chain at male meiosis, suggesting an evolutionary link between mammal and bird sex chromosome systems, which were previously thought to have evolved independently. Expand
Sex from W to Z: evolution of vertebrate sex chromosomes and sex determining genes.
TLDR
It is suggested that sex determining genes can be made redundant, and replaced by control at another step of a conserved sex determining pathway, and how choice of a gene as a sex switch has led to the evolution of new sex chromosome systems. Expand
Comparative mapping of Z-orthologous genes in vertebrates: implications for the evolution of avian sex chromosomes
TLDR
The synteny of chicken Z-linked genes in zebrafish, which is the best-mapped teleost genome so far, argues in favour of a more recent evolution of the avian Z chromosome, compared with the mammalian X. Expand
Evolution of the human X – a smart and sexy chromosome that controls speciation and development
TLDR
The origin of the human X, and the evolution of dosage compensation and gene content, is discussed, in the light of recent demonstrations that particular functions in sex and reproduction and cognition have accumulated on it. Expand
Conserved synteny between the chicken Z sex chromosome and human chromosome 9 includes the male regulatory gene DMRT1: a comparative (re)view on avian sex determination
TLDR
Comparative gene mapping revealed that several genes on human chromosome 9 (HSA 9) have homologs on the chicken Z chromosome (GGA Z), indicating the common ancestry of large parts of GGA Z and HSA 9 and a Z-linked chicken ortholog of DMRT1, which has been implicated in XY sex reversal in humans.

TLDR
The addition–attrition hypothesis predicts that the pseudoautosomal region of the human X is merely the last relic of the latest addition, and evolved functions in male sex determination and differentiation distinct from the general functions of their X‐linked partners. Expand
Sex chromosomes, sex-linked genes, and sex determination in the vertebrate class amphibia.
TLDR
The genes located on the amphibian sex chromosomes lead to the conclusion that there is no common ancestral or conserved sex-linkage group, and despite the accumulated evidence that GSD is operating in Anura and Urodela, there is little substantial information about how it functions. Expand
Comparative Painting Reveals Strong Chromosome Homology Over 80 Million Years of Bird Evolution
TLDR
It is found that the nine macrochromosomes show remarkable homology between the two species, indicating strong conservation of karyotype through evolution, and that ratite sex chromosomes are largely homologous. Expand

TLDR
The Z-linked gene, DMRT1, supports the Z-dosage model of avian sex determination, and two novel W-linked genes, ASW and FET1, represent candidate female determinants. Expand
