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… 
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.
Sex Chromosomes and the Evolution of Sexual Dimorphism: Lessons from the Genome
  • J. Mank
  • Biology
    The American Naturalist

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.
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.
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.
Rethinking our assumptions about the evolution of bird song and other sexually dimorphic signals

  • 2015
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.
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.
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.
Divergent artificial selection for female reproductive investment has a sexually concordant effect on male reproductive success
TLDR
It is demonstrated that selection for increased egg investment in females positively affects male reproductive success both in competitive and non‐competitive mating situations, and suggests that, in this system, selection on reproductive function is sexually concordant.
Masculinization of the X Chromosome in the Pea Aphid
TLDR
The accumulation of sexually antagonistic mutations on the aphid X chromosome is investigated and it is argued that other mechanisms than the resolution of sexual antagonism may lead to sex-biased gene expression could hardly explain the observed difference between X and autosomes.

FURTHER EVIDENCE AGAINST MEIOTIC‐DRIVE MODELS OF HYBRID STERILITY
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.

A test of the role of meiotic drive in fixing a pericentric inversion.
TLDR
Some chromosome rearrangements, including translocations and pericentric inversions, make their heterozygous carriers semisterile because recombination within the arrangement yields aneuploid gametes, and it is difficult to explain these transitions because they would be opposed by natural selection.
The Genetical Theory of Natural Selection
TLDR
Although it is true that most text-books of genetics open with a chapter on biometry, closer inspection will reveal that this has little connexion with the body of the work, and that more often than not it is merely belated homage to a once fashionable study.

TLDR
The author's work fills a need for reference material that takes into account the last half century of data on hybridization in birds, and will make fascinating reading for anyone interested in birds and the natural world.
