Sex chromosomes—particularly the human Y—have been a source of fascination for
decades because of their unique transmission patterns and their peculiar cytology. The …

Differentiated sex chromosomes in mammals and other vertebrates evolved independently
but in strikingly similar ways. Vertebrates with differentiated sex chromosomes share the …

Although iron is required to sustain life, its free concentration and metabolism have to be
tightly regulated. This is achieved through a variety of iron-binding proteins including …

Sex in birds is chromosomally based, as in mammals, but the sex chromosomes are different
and the mechanism of avian sex determination has been a long-standing mystery,,. In the …

In birds, males are the homogametic sex (ZZ) and females the heterogametic sex (ZW).
Primary sex determination is thought to depend on a sex chromosome gene dosage …

Chinese tongue sole is a marine fish with ZW sex determination. Genome sequencing
suggested that the Z-linked dmrt1 is a putative male determination gene, but direct genetic …

The genes that determine the development of the male or female sex are known in
Caenorhabditis elegans, Drosophila, and most mammals. In many other organisms the …

The only molecular similarity in sex determination found so far among phyla is between the
Drosophila doublesex (dsx) and Caenorhabditis elegans mab-3 genes. dsx and mab-3 …

To help understand mechanisms of vertebrate genome evolution, we have compared
zebrafish and tetrapod gene maps. It has been suggested that translocations are fixed more …

In the XX/XY sex-determining system, the Y-linked SRY genes of most mammals and the
DMY/Dmrt1bY genes of the teleost fish medaka have been characterized as sex …
