The Role of Genetics in Sex Diversity. [PDF]

Med Genet, 2023
Sex is a major and complex feature of individual development and concerns all levels of the human appearance – from cells to tissues to hormones to organs to behaviour. It marks embodiment and is the reference for gender. And it may also be the most controversial feature of “the” human body.

ON GENETIC SEGREGATION AND THE EVOLUTION OF SEX [PDF]

Evolution, 1992
It has recently been argued that because the genetic load borne by an asexual species resulting from segregation, relative to a comparable sexual population, is greater than two, sex can overcome its twofold disadvantage and succeed. We evaluate some of the assumptions underlying this argument and discuss alternative assumptions.

SEX DETERMINATION, SEX RATIOS, AND GENETIC CONFLICT [PDF]

Annual Review of Ecology and Systematics, 1998
▪ Abstract  Genetic mechanisms of sex determination are unexpectedly diverse and change rapidly during evolution. We review the role of genetic conflict as the driving force behind this diversity and turnover. Genetic conflict occurs when different components of a genetic system are subject to selection in opposite directions.

Mapping and Validation of the Major Sex-Determining Region in Nile Tilapia (Oreochromis niloticus L.) Using RAD Sequencing [PDF]

, 2013
Sex in Oreochromis niloticus (Nile tilapia) is principally determined by an XX/XY locus but other genetic and environmental factors also influence sex ratio.

Mapping of the Sex Determining Region on Linkage Group 12 of Guppy (Poecilia reticulata)

G3: Genes, Genomes, Genetics, 2019
Poecilia reticulata is one of the most popular ornamental fish species with a higher demand for males due to their large colorful fins. The objectives of this study were mapping of the sex-determining (SD) region on linkage group 12 of guppy, and ...

Identification of a sex-linked SNP marker in the salmon louse (Lepeophtheirus salmonis) using RAD sequencing [PDF]

, 2013
The salmon louse (Lepeophtheirus salmonis (Krøyer, 1837)) is a parasitic copepod that can, if untreated, cause considerable damage to Atlantic salmon (Salmo salar Linnaeus, 1758) and incurs significant costs to the Atlantic salmon mariculture ...

Evolutionary strata on the X chromosomes of the dioecious plant Silene latifolia: Evidence from new sex-linked genes [PDF]

, 2007
Despite its recent evolutionary origin, the sex chromosome system of the plant Silene latifolia shows signs of progressive suppression of recombination having created evolutionary strata of different X-Y divergence on sex chromosomes. However, even after

Sex Determination: Genetic Dominance in Oomycete Sex [PDF]

Current Biology, 2020
Oomycetes are notorious plant pathogens. It is known that genetically distinct oomycete strains can mate to increase their genetic diversity and virulence. A new paper finally reveals the genomic locus that may govern sexual compatibility in one oomycete species.
