11. The Buctzotz and the Campeche reported a higher than average gene flow and / or effective population size . 12. Normally the effective population size , which is smaller than the total population, is used to determine these probabilities. 13. The effective population size is most commonly measured with respect to the heterozygosity is equal to 4N \ mu. 14. The sojourn effective population size can therefore be estimated empirically by dividing the nucleotide diversity by the mutation rate. 15. The Lost Pines population has undergone drastic contractions in effective population size between 3000 and 30 000 years bp. 16. This practice has significantly decreased the effective population size within the small ( < ) range of natural occurrence. 17. Additionally they estimated the effective population size of the common ancestor of humans and chimpanzees to be ~ 100, 000. 18. Where u is the mutation rate, g is the generation time, and N _ e is the effective population size . 19. I might do a simple graphic with Matlab to show how different sex ratios can reduce the effective population size . 20. The number of individuals in a population is not critical, but instead a measure known as the effective population size .
