MORE ON NEI AND ROYCHOUDHURY'S SAMPLING VARIANCES OF HETEROZYGOSITY AND GENETIC DISTANCE

[摘要] The inequality relationship between the expected values of ( jx-g )2 and ( ĝ-g )2, where jx is a biased and ĝ is an unbiased estimate of population homozygosity g , were examined earlier by Nei and Roychoudhury (1974) and later by Mitra (1975). The improvement in the inequality still left much to be desired. In this paper a lower boundary of g has been obtained which may be regarded as ultimate for ensuring a smaller expected value of ( jx-g )2 than the corresponding value of ( ĝ-g )2.
