IN a thLoughtful note in the AMERICAN NATURALIST of MayJune, 1929, entitled "Fisher's Theory of Dominance," Professor Sewall Wright gives the results of his calculations as to the intensity of the selective agency to wilichl I called attention, and reaches a figure so 'extremely slow' as to make its efficacy seem ihiglly questionable.'' Since Professor Wright has carried out independently some of the calculations given in my original paper (April, 1928), and expresses the results in a different… 

A Note on the Mathematical Theory of the Evolution of Dominance

A number of the points which arise in the mathematical analysis of Fisher's theory of the evolution of dominance are discussed, which are perhaps of minor genetical interest in the overall problem of dominance.

Further notes on the evolution of dominance

Fisher's formula has been discussed recently by the author, an analysis is made of a process which Parsons and Bodmer (1961) suggest may lead to the evolution of dominance, various factors concerned in the Evolution of dominance process are summarised and their relative importance discussed.

The R. A. Fisher—Sewall Wright Controversy

The intense controversy between R. A. Fisher and Sewall Wright, which lasted from 1929 until Fisher’s death in 1962, was both highly visible ana very influential in modern evolutionary biology. The

R.A. Fisher's contributions to genetical statistics.

Some of Fisher's major contributions to the foundations of statistical genetics are traced, and his interactions with Wright and with Haldane which contributed to the development of the subject are traced.

On the evolution of dominance

Fisher's theory of the evolution of dominance states that if an unfavourable gene is continuously being produced by mutation, other genes which modify the action of this gene will eventually be selected which will give individuals carrying the gene a phenotype resembling the favoured wild-type phenotype.

Dominance Modifiers of Scute in Drosophila Pseudoobscura.

Investigation of the manifestatioi of the gene Scute in heterozygotes with various different strains of race A as well as race B and hoped that some experimental evidence bearing on the above problems might be obtained in Drosophila pseudoobscura.


It is concluded that the evolution of dominance by the selection of modifiers of the phenotypes of deleterious mutations has a role as the explanation of the dominance found in many cases of selection through visual predation and that the selection mechanism long claimed to be ineffective will be effective under certain special conditions that may be different from those Fisher proposed.

Explaining how and explaining why: developmental and evolutionary explanations of dominance

This paper argues that one need not treat these explanations of dominance as exclusive, and illustrates how biological explanation is a multi-level task, requiring both a “top-down” approach to understanding how a pattern of inheritance or trait might be maintained in populations, as well as “bottom-up” modeling of the dynamics of gene expression.
