Is the Y chromosome disappearing?—Both sides of the argument [PDF]

, 2011
On August 31, 2011 at the 18th International Chromosome Conference in Manchester, Jenny Graves took on Jenn Hughes to debate the demise (or otherwise) of the mammalian Y chromosome.

ATR is a multifunctional regulator of male mouse meiosis

Nature Communications, 2018
ATR kinase is required for meiosis in non-mammalian model organisms. Here the authors demonstrate, using a tissue-specific knockout approach, that ATR is also essential for male meiosis in mouse, regulating meiotic recombination and synapsis.

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.

Sex Chromosome Turnover in Moths of the Diverse Superfamily Gelechioidea [PDF]

, 2019
Sex chromosomes play a central role in genetics of speciation and their turnover was suggested to promote divergence. In vertebrates, sex chromosome–autosome fusions resulting in neo-sex chromosomes occur frequently in male heterogametic taxa (XX/XY ...

A specific insertion of a solo-LTR characterizes the Y chromosome of Bryonia dioica (Cucurbitaceae) [PDF]

, 2010
Background: Relatively few species of flowering plants are dioecious and even fewer are known to have sex chromosomes. Current theory posits that homomorphic sex chromosomes, such as found in Bryonia dioica (Cucurbitaceae), offer insight into the early ...

Reference genome and transcriptome informed by the sex chromosome complement of the sample increase ability to detect sex differences in gene expression from RNA-Seq data

Biology of Sex Differences, 2020
Background Human X and Y chromosomes share an evolutionary origin and, as a consequence, sequence similarity. We investigated whether the sequence homology between the X and Y chromosomes affects the alignment of RNA-Seq reads and estimates of ...

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.

Sex chromosomal dimorphisms narrated by X-chromosome translocation in a spiny frog (Quasipaa boulengeri)

Frontiers in Zoology, 2018
Background In the general model of sex chromosome evolution for diploid dioecious organisms, the Y (or W) chromosome is derived, while the homogametic sex presumably represents the ancestral condition.

The inexorable spread of a newly arisen neo-Y chromosome [PDF]

, 2008
This work was financially supported by a Natural Environment Research Council grant to RAN. (NER-B-S-2003-00859) and a studentship from Queen Mary University of London to PV.A newly arisen Y-chromosome can become established in one part of a species ...

Assembly of the threespine stickleback Y chromosome reveals convergent signatures of sex chromosome evolution [PDF]

, 2020
Background: Heteromorphic sex chromosomes have evolved repeatedly across diverse species. Suppression of recombination between X and Y chromosomes leads to degeneration of the Y chromosome.
