Many public sector maize recurrent selection programs have been designed based on additive genetic expectations. Populations have been managed as large metapopulations with the assumption that population size must be very large because inbreeding due to finite size causes a linear reduction in genetic variance; we show that in BS13(S)C0 such ...

Genetic drift in sharing methods
Proceedings of the First IEEE Conference on Evolutionary Computation. IEEE World Congress on Computational Intelligence, 2002Adding a sharing method to a genetic algorithm promotes the formation and maintenance of stable subpopulations. The paper explores the limits of sharing by deriving closed-form expressions for the expected time to disappearance of a subpopulation.

The Effect of Genetic Drift in a Young Genetically Isolated Population
Annals of Human Genetics, 2005SummaryThe genetic make‐up of genetically isolated populations may differ from a general population as a result of genetic drift and founder effects. We assessed the extent of this deviation in a recently isolated population located in the southwest of the Netherlands and studied as part of the Genetic Research in Isolated Population (GRIP) program.

Population Genetics: Consanguinity, Genetic Drift
1997Considerations in the preceding chapters presume random mating, and Hardy-Weinberg proportions are assumed to hold true. However, such assumptions are an abstraction. In modern outbreeding populations mating may approximate randomness for some genetic traits, such as blood groups and enzyme types, but is certainly nonrandom for some traits and some ...

Genetic drift is a random process that can lead to the fixation of alleles, but at the cost of losing alleles, especially those with low frequencies, and to increased homozygosity in the population. This process is described for an idealised population and its effect illustrated on different population sizes.

Random changes are difficult to discuss, in that we cannot (usually) say that some specific change will happen, only that the change is probable or improbable. Statements involving probability are apt to produce discomfort in the reader, a vague sense of entering through a shop door labelled “only abstractions sold here”.
