Abstract The genetic basis of sexual dimorphisms is an intriguing problem of evolutionary genetics because dimorphic traits are limited to one sex. Such traits can arise genetically in two ways. First, the alleles that cause dimorphisms could be limited in expression to only one sex at their first appearance. Alternatively, dimorphism alleles could initially be expressed in both sexes, but subsequently be repressed or promoted in only one sex by the evolution of modifier genes or regulatory… Expand
Genetic Considerations in the Evolution of Sexual Dimorphism
TLDR
Overall, this thesis concludes that sexual dimorphism can evolve by processes that generate novel sexualDimorphism or that take advantage of pre-existingdimorphism. Expand
Sex Chromosomes and the Evolution of Sexual Dimorphism: Lessons from the Genome
  • J. Mank
  • Biology, Medicine
  • The American Naturalist
  • 2008
TLDR
Genomic analysis indicates that there is indeed a relationship between sexual dimorphism and the sex chromosomes, but the connection is far more complicated than current theory allows, and this may ultimately require a reexamination of the assumptions so that predictions match the accumulating empirical data. Expand
Insights into the genetic architecture of sexual dimorphism from an interspecific cross between two diverging Silene (Caryophyllaceae) species
TLDR
Support for an accumulation of QTL on the sex chromosomes is found and that sex differences explained a large proportion of the variance between species, suggesting that both natural and sexual selection contributed to species divergence. Expand
A morphological integration perspective on the evolution of dimorphism among sexes and social insect castes.
TLDR
This work extends the conceptual framework and methods of morphological integration to hypothesize that dimorphic traits tend to be less integrated between sexes or social castes, and finds a negative association between dimorphism and the degree of integration between sexes. Expand
A genetic mechanism for sexual dichromatism in birds
TLDR
Dichromatism in mosaic canaries is explained by differential carotenoid degradation in the integument, rather than sex-specific variation in physiological functions such as pigment uptake or transport, and results suggest that differences in ornamental coloration between sexes can evolve through simple molecular mechanisms controlled by genes of major effect. Expand
A multivariate view of the evolution of sexual dimorphism
TLDR
Although the number of multivariate sexual dimorphism studies is low, almost all support sex‐specific differences in the G (variance‐covariance) matrix; G matrices can differ with respect to size and/or orientation, affecting the response to selection differently between the sexes. Expand
The Regulation and Evolution of a Genetic Switch Controlling Sexually Dimorphic Traits in Drosophila
TLDR
It is shown that the HOX protein Abdominal-B (ABD-B) and the sex-specific isoforms of Doublesex (DSX) directly regulate a bab cis-regulatory element (CRE), which evolved through multiple fine-scale changes within this CRE, whose ancestral role was to regulate other dimorphic features. Expand
Rethinking our assumptions about the evolution of bird song and other sexually dimorphic signals
TLDR
It is proposed that these new findings do not necessarily contradict previous research, but rather they disagree with some of the authors' assumptions about the evolution of sexual dimorphisms in general and female song in particular. Expand
The Resolution of Sexual Antagonism by Gene Duplication
TLDR
It is shown that sexual antagonism can favor the fixation and maintenance of gene duplicates, eventually leading to the evolution of sexually dimorphic genetic architectures for male and female traits. Expand
Sex-determining chromosomes and sexual dimorphism: insights from genetic mapping of sex expression in a natural hybrid Fragaria × ananassa subsp. cuneifolia
TLDR
The results suggest that hybrids experience some disruption of dimorphism in secondary sexual traits, as well as novel location and number of quantitative trait locus (QTL) affecting sex function. Expand

Hormonal basis of sexual dimorphism in birds: implications for new theories of sexual selection.
TLDR
The surprising relationships between dimorphism and gonadal steroids in birds have important consequences for the current debate concerning the evolution of biological signals and, in particular, the immunocompetence-handicap principle. Expand
FURTHER EVIDENCE AGAINST MEIOTIC‐DRIVE MODELS OF HYBRID STERILITY
  • J. Coyne, H. A. Orr
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1993
TLDR
A direct experimental test of the meiotic-drive explanation for Haldane's rule is provided, which explains only hybrid sterility and not inviability, and mutations causing preferential segregation of a chromosome may arise frequently, but are more likely to increase in frequency when on sex chromosomes than on autosomes.

Chance caught on the wing: cis-regulatory evolution and the origin of pigment patterns in Drosophila
TLDR
It is shown that the evolution of this spot involved modifications of an ancestral cis-regulatory element of the yellow pigmentation gene, which has gained multiple binding sites for transcription factors that are deeply conserved components of the regulatory landscape controlling wing development.

The transmission of secondary sexual characters in pheasants
TLDR
Pheasant breeding experiments commenced over eight years ago after reading Mr Punnett's "Mendelism" opened up a study so fascinating that various schemes were undertaken to ascertain whether pheasant crosses would follow Mendel's law. Expand
THE LOCUS OF EVOLUTION: EVO DEVO AND THE GENETICS OF ADAPTATION
  • H. Hoekstra, J. Coyne
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 2007
TLDR
There is no theoretical or empirical basis for the evo devo contention that adaptations involving morphology evolve by genetic mechanisms different from those involving physiology and other traits, and substantial data on the genetic basis of adaptation from both genome-wide surveys and single-locus studies are examined.

Why are female birds ornamented?
  • Amundsen
  • Biology, Medicine
  • Trends in ecology & evolution
  • 2000
TLDR
Comparison evidence suggests that female ornaments have evolved quite independently of male showiness, and new theoretical models predict that both male mate choice and female contest competition will occur under certain circumstances. Expand

Transvection effects in Drosophila.

  • 2002
TLDR
Several cases of transvection require Zeste, a DNA-binding protein that is thought to facilitate homolog interactions by self-aggregation, and in at least one case (transvection of the iab-5,6,7 region of the BX-C), transvections is independent of synapsis within and surrounding the interacting gene.
