The age of an allele in a finite population

Abstract

The age of an allele segregating in a finite population may be defined in two ways. They are (1) the age of a mutant gene that has never reached fixation in the population, and (2) the age including any fixation period in the past. Theoretical expressions for these are derived on the assumption that every mutant is unique. © 1974, Cambridge University Press. All rights reserved.
