Sex chromosomes and speciation
Proceedings of the Royal Society of London. Series B: Biological Sciences, 1991Studies of reproductive isolation between animal species have shown (i) that if one sex of the hybrids between two species is sterile or inviable, it is usually the heterogametic sex (Haldane's rule), and (ii) the genes on the sex chromosomes play a particularly large role in hybrid sterility and inviability.

Sex chromosome aneuploidies comprise a relatively common group of chromosome disorders characterized by the loss or gain of one or more sex chromosomes. We discuss five of the better-known sex aneuploidies: Turner syndrome (XO), Klinefelter syndrome (XXY), trisomy X (XXX), XYY, and XXYY.

The evolution of sex chromosomes
Cytogenetic and Genome Research, 2002Mammalian sex chromosomes appear, behave and function differently than the autosomes, passing on their genes in a unique sex-linked manner. The publishing of Ohno’s hypothesis provided a framework for discussion of sex chromosome evolution, allowing it to be developed and challenged numerous times. In this report we discuss the pressures that drove the

CRC Critical Reviews in Clinical Laboratory Sciences, 1981
A critical and comprehensive review of the major sex chromosome disorders. The introduction briefly outlines the cytogenetic background to these disorders and refers to earlier reviews. The paper then reviews the clinical and psychiatric aspects of the various chromosome disorders.

Sex Chromosomes and Sex Chromosome Abnormalities
1999It can be argued that the sex chromosomes are the most important pair of chromosomes given their role in determining gender and, therefore, allowing for reproduction and procreation. Considered together, sex chromosome aneuploidies are the most common chromosome abnormalities seen in liveborn infants, children, and adults.

The variability is in the sex chromosomes.
Evolution; international journal of organic evolution, 2013Sex differences in the mean trait expression are well documented, not only for traits that are directly associated with reproduction. Less is known about how the variability of traits differs between males and females. In species with sex chromosomes and dosage compensation, the heterogametic sex is expected to show larger trait variability ("sex ...

The Evolution of Sex Chromosomes
Science, 1991Structurally distinct sex chromosomes (X and Y) are the most familiar mode of genetic sex determination and have evolved independently in many different taxa. The evolutionary paths by which their characteristic properties may have evolved are reviewed.

Sex chromosomes and sex determination in reptiles
Current Opinion in Genetics & Development, 2005Reptiles occupy a crucial position with respect to vertebrate phylogeny, having roamed the earth for more than 300 million years and given rise to both birds and mammals. To date, this group has been largely ignored by contemporary genomics technologies, although the green anole lizard was recently recommended for whole genome sequencing.

On the origin of sex chromosomes
BioEssays, 1999In all living forms, the organization of the genetic material must enable two universally fundamental functions: the elaboration of biological properties and their transmission. In spite of these inexorable commonalties, genomes have a bewildering variety of forms, with differences occurring not only among distant taxa but also, in many instances ...

Sex Chromosomes and Sex Determination in Lepidoptera
Sexual Development, 2007The speciose insect order Lepidoptera (moths and butterflies) and their closest relatives, Trichoptera (caddis flies), share a female-heterogametic sex chromosome system. Originally a Z/ZZ (female/male) system, it evolved by chromosome rearrangement to a WZ/ZZ (female/male) system in the most species-rich branch of Lepidoptera, a monophyletic group ...
