A MODEL ALLOWING CONTINUOUS VARIATION IN ELECTROPHORETIC MOBILITY OF NEUTRAL ALLELES

1 Department of Biology, University of Louisville, Louisville, Kentucky 40208

The infinite-sites model with no recombination is extended to include mutations that affect electrophoretic mobility. The model allows the effect of a single-site mutation to have a continuous effect on mobility. Formulae are obtained for the variance of electrophoretic mobility of alleles after an arbitrary length of time. A special case of the general model is the case of stepwise production of neutral alleles with an arbitrary number of steps.
