Estimating Effective Population Size Using Pedigree Data

Abstract

Determining the sample size is the most important factor to effect of reliability of all scientific studies. The reliability of genetic parameter estimations obtained from phenotypic data with using pedigree depends on sufficiency of sample size. In this study was aimed to determine the effective population size for cattle, sheep and goat breeds. For this aim, methods depend on sex ratio, variance of progeny size and inbreeding rate were compared. Results indicated that the methods depends on variance of progeny size was suggestible for interested breeds.
