Darwin on the Proportion of the Sexes and General Fertility: Discovery and Rejection of Sex Ratio Evolution and Density-Dependent Selection

In The Descent of man and selection in relation to sex (1871) Darwin put forward theoretical principles which foreshadowed two breakthroughs of evolutionary thinking in the twentieth century: sex

A theory of Fisher's reproductive value

A rigorously defined and very general structure justifies, and shows the unity of concept behind, Fisher's uses of reproductive value as measuring the significance for evolutionary processes of an individual and a class, and as an evolutionary maximand under natural selection.

Düsing's mathematical account of the influence of natural selection on the sex ratio based on the same argument that Darwin had advanced in The Descent of Man is given.

Sex ratios and social evolution

Models of sex ratio evolution

The models used in this work are of two general kinds: expected-future-fitness or tracer-gene models that ask how a given sex allocation will affect the future frequencies of neutral genes carried by the allocating parent, and explicit population-genetic models that consider the dynamics of alleles that determine alternative parental sex allocation phenotypes.

Sex Ratio Theory, Ancient and Modern: An Eighteenth-Century Debate about Intelligent Design and the Development of Models in Evolutionary Biology

The design argument for the existence of God took a probabilistic turn in the 17 and 18 centuries, inspired by the emerging mathematical theory of probability and characterized in terms of the mathematical concept of probability.

The Selfish Gene Revisited: Reconciliation of Williams-Dawkins and Conventional Definitions

It is seen that recombination can be triggered by the shift in base composition at genic boundaries, and the Williams-Dawkins definition approaches the conventional definitions.

Perspectives Anecdotal, Historical and Critical Commentaries on Genetics The Genetical Theory of Natural Selection

So melancholy a neglect of Darwin’s work suggests reflections upon the use of those rare and precious possessions of man—great books. It was, we believe, the custom of the late Professor Freeman to

Evolution of sex-ratio: Brief review with mathematical study of some simple novel models

  • P. Otto

    Genetics and molecular biology
  • 2021
Three novel models are presented, in which the shift on the progeny sex-ratio depends on the number of copies of a mutant allele present in the parental pair, and it is shown that autosomal mutations that alter the usual sex-Ratio are eliminated from the population.

A gene's-eye view of sexual antagonism

A gene's-eye-view approach is developed that reconciles the classic view with these recent discordant results, separating a gene's valuation of female versus male fitness from its ability to induce fitness effects in either sex, and is used to generate new comparative predictions for sexually antagonistic evolution.



The Theoretical Genetics of the Sex Ratio.

In several species of Drosophila there is an X-linked gene causing males which carry it to produce almost all daughters and an autosomal gene which, in the presence of this X- linked gene, leads to the production of almost all sons.

Natural Selection and the Sex Ratio: The Approach to Equilibrium

Bodmer and Edwards' (1960) mathematical analysis of the action of Natural Selection on the sex ratio is extended to cover cases in which the equilibrium tertiary sex ratio is other than one half. It
