SEX CHROMOSOMES IN AMNIOTA [PDF]

Evolution, 1957
During the past 25 years the chromnosomal conditions in Vertebrates have been the subject of a great many investigations. With some justification it has been hoped that such work might add to our present knowledge of the evolutionary relation between the different classes of Vertebrates and, in this connection, special attention has been given to the ...

Conflict over condition-dependent sex allocation can lead to mixed sex-determination systems [PDF]

, 2014
Theory suggests that genetic conflicts drive turnovers between sex-determining mechanisms, yet these studies only apply to cases where sex allocation is independent of environment or condition.

Sex Chromosome Drive [PDF]

Cold Spring Harbor Perspectives in Biology, 2014
Sex chromosome drivers are selfish elements that subvert Mendel's first law of segregation and therefore are overrepresented among the products of meiosis. The sex-biased progeny produced then fuels an extended genetic conflict between the driver and the rest of the genome.

Sex determination without sex chromosomes [PDF]

Philosophical Transactions of the Royal Society B, 2021
Abstract With or without sex chromosomes, sex determination is a synthesis of many molecular events that drives a community of cells towards a coordinated tissue fate. In this review, we will consider how a sex determination pathway can be engaged and stabilized without an inherited genetic determinant.

Remnant of Unrelated Amniote Sex Chromosomal Linkage Sharing on the Same Chromosome in House Gecko Lizards, Providing a Better Understanding of the Ancestral Super-Sex Chromosome

Cells, 2021
Comparative chromosome maps investigating sex chromosomal linkage groups in amniotes and microsatellite repeat motifs of a male house gecko lizard (Hemidactylus frenatus, HFR) and a flat-tailed house gecko lizard (H.

Early events in the evolution of the Silene latifolia Y chromosome: Male specialization and recombination arrest [PDF]

, 2007
Understanding the origin and evolution of sex chromosomes requires studying recently evolved X-Y chromosome systems such as those in some flowering plants.

Snake W Sex Chromosome: The Shadow of Ancestral Amniote Super-Sex Chromosome

Cells, 2020
Heteromorphic sex chromosomes, particularly the ZZ/ZW sex chromosome system of birds and some reptiles, undergo evolutionary dynamics distinct from those of autosomes. The W sex chromosome is a unique karyological member of this heteromorphic pair, which

Sex determination in mythology and history [PDF]

, 2005
The history of ideas on how the sexes became divided spans at least three thousand years. The biblical account of the origin of Eve, and the opinions of the philosophers of classical Greece, have unexpected bearings on present-day ideas.

A trans-species missense SNP in Amhr2 is associated with sex determination in the tiger pufferfish, Takifugu rubripes (fugu). [PDF]

PLoS Genetics, 2012
Heterogametic sex chromosomes have evolved independently in various lineages of vertebrates. Such sex chromosome pairs often contain nonrecombining regions, with one of the chromosomes harboring a master sex-determining (SD) gene. It is hypothesized that

Evolution and conservation of Characidium sex chromosomes [PDF]

, 2017
Fish species exhibit substantial variation in the degree of genetic differentiation between sex chromosome pairs, and therefore offer the opportunity to study the full range of sex chromosome evolution. We used restriction-site associated DNA sequencing (
