Abstract
  • Surname distributions, used for the studies on genetic structure of populations, fit very well Fisher's logarithmic distribution, by which expected number of species and individuals in samples of animal populations is estimated. The parameter alpha, measuring \"surnames diversity\" (gene diversity) in different subpopulations, is independent of the sample size but is influenced by the way in which each subpopulation area is sampled. The estimation of the effect of the number of subdivisions on alpha measures how a population deviates from panmixia and enlightens on the past migratory processes. (literal)
