There seems little probability of direct evidence upon so subtle a question. I have myself attached a good deal of importance, in other connections, to gene ratios held in stable equilibrium, though it never occurred to me that such a state was universal. Even if it were nearly so, the conditions on which the stability rests must be liable to change; stability may turn to instability, a transient state, admittedly, but one in which a minute, but steadily increasing, selective intensity would be…

Science has largely advanced by the analytic procedure of isolating the effects of single factors in carefully controlled experiments. The task of science is not complete, however, without synthesis:

The phenomenon of dominance has interested research workers since the rediscovery of Mendelism at the turn of the century. Fisher was, however, interested in the origin of dominance. In 1928 he

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.

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 history of several intellectual and methodological traditions that have contributed to this debate are traced, including experimental genetics, theoretical population genetics and theoretical biochemistry, and it is argued that contrary to the prevalent view, the evolution of dominance is not a resolved issue.

The probability distribution of gene-differences in relation to selection, mutation, and random extinction

In order to determine the mathematical form of the distribution of gene frequencies in a population, R. A. Fisher (1, 2) applied two different but complementary methods. First, differential equations
