Sex determination studies in two species of teleost fish, Oreochromis niloticus and Leporinus elongatus
(Acad Sinica Inst Zoology, 1996-10-01)
Genetic analyses of sex determination have identified sex chromosomes in many teleost fish species. However, there are several cases for which sex ratios do not fit perfectly with the expectations of heterogametic systems, ...
Sex and neo-sex chromosomes in Orthoptera: a review
(Orthopterists' Society, 2010-12)
We review historical and pioneering work as well as recently published papers about orthopteran sex chromosomes and neo-sex mechanisms, highlighting Michael White's significant contributions. Meiotic research in Orthoptera ...
Sex determination studies in two species of teleost fish, Oreochromis niloticus and Leporinus elongatus
(Acad Sinica Inst Zoology, 2014)
RADSex: A computational workflow to study sex determination using restriction site-associated DNA sequencing data
(Wiley-Blackwell, 2021-03-09)
The study of sex determination and sex chromosome organization in nonmodel species has long been technically challenging, but new sequencing methodologies now enable precise and high-throughput identification of sex-specific ...
Heteromorphic Sex Chromosomes and Their DNA Content in Fish: An Insight through Satellite DNA Accumulation in Megaleporinus elongatus
(Karger, 2020-04-01)
The repetitive DNA content of fish sex chromosomes provides valuable insights into specificities and patterns of their genetic sex determination systems. In this study, we revealed the genomic satellite DNA (satDNA) content ...

Genetic analyses of sex determination have identified sex chromosomes in many teleost fish species. However, there are several cases for which sex ratios do not fit perfectly with the expectations of heterogametic systems, ...
Sex determination in neotropical fish: implications ranging from aquaculture technology to ecological assessment
(Academic Press Inc Elsevier Science, 2019-03)
The high biodiversity of fish in the Neotropical region contrasts with scarce or biased studies on the mechanisms involved in the sex determination in members of this fauna. In this review, we attempted to compile the ...
Complementary Sex Determination in the Parasitic Wasp Diachasmimorpha longicaudata
(Public Library of Science, 2015-03-19)
We studied the sex determination in Diachasmimorpha longicaudata, a parasitoid braconid wasp widely used as biological control agent of fruit pest tephritid flies. We tested the complementary sex determination hypothesis ...
SEX RATIO VARIATION IN THE LESSONIA NIGRESCENS COMPLEX (LAMINARIALES, PHAEOPHYCEAE): EFFECT OF LATITUDE, TEMPERATURE, AND MARGINALITY
(WILEY, 2011)
Little is known about variation of sex ratio, the proportion of males to females, in natural populations of seaweed, though it is a major determinant of the mating system. The observation of sexual chromosomes in kelps ...
Male sex workers: Practices, contexts, and vulnerabilities for HIV acquisition and transmission
(Elsevier, 2015)
Male sex workers who sell or exchange sex for money or goods encompass a very diverse population across and within countries worldwide. Information characterising their practices, contexts where they live, and their needs ...
