Genetic drift and estimation of effective population size.
The statistical properties of the standardized variance of gene frequency changes (a quantity equivalent to Wright's inbreeding coefficient) in a random mating population are studied, and new formulae for estimating the effective population size are developed. The accuracy of the formulae depends on the ratio of sample size to effective size, the number of generations involved (t), and the numb...
متن کاملEffective/census population size ratio estimation: a compendium and appraisal
With an ecological-evolutionary perspective increasingly applied toward the conservation and management of endangered or exploited species, the genetic estimation of effective population size (N(e)) has proliferated. Based on a comprehensive analysis of empirical literature from the past two decades, we asked: (i) how often do studies link N(e) to the adult census population size (N)? (ii) To w...
متن کاملEffective population size
What is it? An aid to calculation in population genetics, introduced by Sewall Wright. The rate of change of the genetic make-up of a population by genetic drift — fluctuations in allele frequencies caused by random sampling — is inversely related to the effective population size, Ne. Ne is measured with reference to an ideal ‘Wright–Fisher’ population. This has a fixed number of N diploid bree...
متن کاملlanguage learning strategies and vocabulary size of iranian efl learners
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
estimation of effective population size in sarabi cattle based on single nucleotide polymorphism markers
the objective of this study was to estimate the effective number of breeders in sarabi cattle population using heterozygote-excess method based on single nucleotide polymorphism markers. data consisted of 20 sarabi cows. snp genotyping was performed using illumina high-density bovine beadchip designed to genotype 777,962 snps. average observed heterozygosity, expected heterozygosity, minor alle...
