The most important issue on which H. J. Muller and Th. Dobzhansky differed was a question that had puzzled plant and animal breeders during most of the first half of the twentieth century. Breeders were concerned with maximizing performance. Dobzhansky was concerned with the potential of the species for further evolution and so was Muller, but his immediate concern was the impact on future generations of a radiation-induced increase in the mutation rate. All three concerns centered on how much… 
Group selection and the development of the biological species concept

The development of what became known as the biological species concept began with a paper by Theodosius Dobzhansky in 1935, and was amplified by a mutualistic interaction between Dobzhansky, Alfred
Golden Generalities and Co-opted Anomalies: Haldane vs. Muller and the Drosophila Group on the Theory and Practice of Linkage Mapping
The authors of the Mechanisms of Mendelian Heredity concluded their discussions of Haldane’s views on a theory of linkage by concluding that the linkage map was an exemplar of high theoretical science at its best.
Fitness Landscapes: An Alternative Theory for the Dominance of Mutation
This article shows that under a very broad range of conditions (and environments), the average dominance of mutation of small effects should be approximately one-quarter as long as adaptation of organisms to their environment can be well described by stabilizing selection on an arbitrary set of phenotypic traits, and provides possible extension of the theory for this class of mutations.
Did Mendelism Transform Plant Breeding? Genetic Theory and Breeding Practice, 1900–1945
None of the bold and general claims made for Mendelism’s revolutionary impact, especially before the First World War, were justified and are thus best seen as rhetoric designed to attract recruits and resources to an emerging field.
On the importance of balancing selection in plants.
It is concluded that while discrete-morph variation provides the most unambiguous cases of protected polymorphism, they represent only a fraction of the balancing selection at work in plants.
H. J. Muller's role in evolutionary biology
M Muller regularly taught a course in evolution, which started with the origins of the universe and of the solar system and ended with science fiction-like speculation about, and hopes for, the future of human evolution.
Agricultural science, plant breeding and the emergence of a Mendelian system in Britain, 1880-1930
Following Thomas P. Hughes’s systems approach in the history of technology, and making use of previously unexamined sources, this dissertation seeks to show that the development of British Mendelism
Deleterious mutations and the genetic variance of male fitness components in Mimulus guttatus.
An application of the "biometric method" for estimating mutational parameters for male fitness characters of the yellow monkeyflower, Mimulus guttatus, finds that, if biometric methods are going to yield useful parameter estimates, they will need to consider mutational models more complicated than those typically employed in experimental studies.
Chance, Variation and Shared Ancestry: Population Genetics After the Synthesis.

In the wake of the transition from Mendelism to genomics, the combination of coalescent theory, DNA sequence variation, and numerical analysis made it possible to integrate contingent aspects of the history of species into a new null model, thus opening a new dimension in the concept of population that the Modern Synthesis formerly considered as a mere gene pool.
Fifty years later: I. Michael Lerner's Genetic homeostasis (1954)--a valiant attempt to integrate genes, organisms and environment.

Genetic Homeostasis is the most original and innovative of Lerner’s books, a testament to what can emerge from the combination of a prepared mind, sabbatical leave, ‘‘Guggenheim’’, solitude and an Italian winter.
