How to make a sex chromosome

AE Wright, R Dean, F Zimmer, JE Mank - Nature communications, 2016 - nature.com

chromosomes. Owing to detailed studies using key model systems, we have a nuanced …

Sex chromosomes as supergenes of speciation: why amphibians defy the rules?

C Dufresnes, PA Crochet - Philosophical Transactions of …, 2022 - royalsocietypublishing.org
As reflected by the two rules of speciation (Haldane's rule and the large X-/Z-effect), sex
chromosomes are expected to behave like supergenes of speciation: they recombine only in …

A rapid rate of sex-chromosome turnover and non-random transitions in true frogs

DL Jeffries, G Lavanchy, R Sermier, MJ Sredl… - Nature …, 2018 - nature.com
The canonical model of sex-chromosome evolution predicts that, as recombination is

Sex determination and sex chromosomes in Amphibia

I Miura - Sexual Development, 2018 - karger.com
Sex chromosomes in most amphibians are homomorphic (undifferentiated) in both sexes
and are characterized by frequent turnover. This is in sharp contrast to sex chromosomes in …

Repeated translocation of a gene cassette drives sex-chromosome turnover in strawberries

JA Tennessen, N Wei, SCK Straub… - PLoS …, 2018 - journals.plos.org
Turnovers of sex-determining systems represent important diversifying forces across
eukaryotes. Shifts in sex chromosomes—but conservation of the master sex-determining …

Sex-chromosome evolution in frogs: what role for sex-antagonistic genes?

N Perrin - … Transactions of the Royal Society B, 2021 - royalsocietypublishing.org
Sex-antagonistic (SA) genes are widely considered to be crucial players in the evolution of
sex chromosomes, being instrumental in the arrest of recombination and degeneration of Y …
