Some population genetic models combining artificial and natural selection pressures: I. one-locus theory.
This paper investigates the consequences of implementing certain specific artificial selection programs on populations taking due account of some natural genetic and ecological forces. A series of culling procedures and models have been examined in considerable detail, and a number of qualitative and quantitative conclusions were drawn. The basic population is taken to be large, effectively of ...
متن کاملGenetic Algorithms: Artificial Selection vs Natural Selection
Genetic Algorithms (GAs) are a stochastic searching and optimizing method inspired by the biological mechanism of natural selection and evolution. To improve the searching power of GAs for complicated problems, many deterministic measures, particularly, experience and/or expert knowledge-based heuristic rules, have been studied in the existing literature. This paper proposes a potentially more ...
متن کاملGenetic Hitchhiking under Heterogeneous Spatial Selection Pressures
During adaptive evolutionary processes substantial heterogeneity in selective pressure might act across local habitats in sympatry. Examples are selection for drug resistance in malaria or herbicide resistance in weeds. In such setups standard population-genetic assumptions (homogeneous constant selection pressures, random mating etc.) are likely to be violated. To avoid misinferences on the st...
متن کاملPopulation- and Quantitative-Genetic Models of Selection Limits*
∗ The author is very pleased to dedicate this paper to John Dudley for his contributions to both maize and quantitative genetics. John answered what must have seemed to be an endless number of trivial questions and I thank him for his patience. Torbert Rocheford and Irwin Goldman also provided valuable input on the Illinois selection lines, and Jean-Luc Jannink for many useful comments on a dra...
متن کاملNatural selection and population dynamics.
To what extent, and under which circumstances, are population dynamics influenced by concurrent natural selection? Density dependence and environmental stochasticity are generally expected to subsume any selective modulation of population growth rate, but theoretical considerations point to conditions under which selection can have an appreciable impact on population dynamics. By contrast, empi...
