Sampling Variances of Heterozygosity and Genetic Distance1
Mathematical formulae for the sampling variances of average heterozygosity and NEI'S genetic distance are developed. These sampling variances are decomposed into their two components, i.e. the inter-locus and intra-locus variances. The relationship between the number of loci and the number of individuals per locus to be examined for estimating average heterozygosity and genetic distance is also...
متن کاملHeterozygosity and Genetic Distance
In the mid-1960s protein electrophoresis revolutionized the study of population genetics and evolution. This technique revealed an extensive amount of genetic polymorphism existing in natural populations and, at the same time, provided a powerful tool to examine the evolutionary relationships of closely related species.1’2 In 1972 I developed a statistical method by which one can measure the ge...
متن کاملOn Nei and Roychoudhury's sampling variances of heterozygosity and genetic distance.
NEI and ROYCHOUNHARY have developed an inequality relationship between the expected values of (j-x - g)-2 and (ĝ - g)-2 where j-x is a biased and g is an unbiased estimate of population homozygosity g. Their inequality is somewhat weak and can be improved, as is demonstrated in this paper.
متن کاملphylogeography and genetic diversity of the lesser mouse- eared bat (myotis blythii) in iran
in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
Estimation of average heterozygosity and genetic distance from a small number of individuals.
The magnitudes of the systematic biases involved in sample heterozygosity and sample genetic distances are evaluated, and formulae for obtaining unbiased estimates of average heterozygosity and genetic distance are developed. It is also shown that the number of individuals to be used for estimating average heterozygosity can be very small if a large number of loci are studied and the average he...
