Journal ArticleDOI
The distribution of allelic effects under mutation and selection.
TL;DR: The Price (1970, 1972) equation is applied to the problem of describing the changes in the moments of allelic effects caused by selection, mutation and recombination at loci governing a quantitative genetic character.
Journal ArticleDOI
An excess of gene expression divergence on the X chromosome in Drosophila embryos: implications for the faster-X hypothesis.
TL;DR: Empirical studies demonstrating increased genetic divergence on the X chromosome could be indicative of either adaptive or non-adaptive evolution, and results are most consistent within the framework of the faster-X hypothesis.

Inclusive Fitness in Finite Deme-structured and Stepping-stone Populations
Peter D. Taylor,Andrew J. Irwin +1 more
TL;DR: A model of altruism in a deme-structured population is examined to verify numerically that the relatedness coefficients provide a correct measure of allele frequency change.
Journal ArticleDOI
A demographic transition altered the strength of selection for fitness and age-specific survival and fertility in a 19th century American population.
TL;DR: It is suggested that this demographic transition in 19th century female populations of Utah has increased the adaptive potential of the Utah population, intensified selection for reproductive traits, and de‐emphasized selection for survival‐related traits.
Journal ArticleDOI
The evolution of group-beneficial traits in the absence of between-group selection.
TL;DR: It is demonstrated that individual-level selection, that is selection within groups can also produce an intermediate frequency of such group-beneficial traits by frequency-dependent selection.
