Sampling Variances of Heterozygosity and Genetic Distance1
نویسنده
چکیده
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 discussed. The utility of the inter-locus variance of heterozygosity for studying the mechanism of maintenance of genetic variability in populations is indicated.

On 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 کاملEstimating microsatellite based genetic diversity in Rhode Island Red chicken
This study aimed to estimate microsatellite based genetic diversity in two lines (the selected RIRS and control line RIRC) of Rhode Island Red (RIR) chicken. Genomic DNA of 24 randomly selected birds maintained at Central Avian Research Institute (India) and 24 microsatellite markers were used. Microsatellite alleles were determined on 6% urea-PAGE, recorded using GelDoc system and the samples ...
متن کاملAnalysis of Genetic Diversity in Berari Goat Population of Maharashtra State
Berari goats are medium sized animals reared mainly for meat purpose. They are predominantly brown and blackish brown in colour with glossy hair and found in Vidarbha region of Maharashtra state. Berari is not a recognized breed but a well established local population of goat which is yet to be fully explored for its phenotypic and genetic aspects. Within population genetic variation was examin...
متن کاملVariance of neutral genetic variances within and between populations for a quantitative character.
The variances of genetic variances within and between finite populations were systematically studied using a general multiple allele model with mutation in terms of identity by descent measures. We partitioned the genetic variances into components corresponding to genetic variances and covariances within and between loci. We also analyzed the sampling variance. Both transient and equilibrium re...
متن کاملEvaluation of Genetic Diversity in Japanese and English White Quail Populations Using Microsatellite Markers
The Japanese and English White quails are widespread strains and belongs to the Galliformes order, Phasianidae family, Coturnix genus and Japonica species. These birds are likely to be well-adapted to the hard conditions and resistance to diseases as it has attained economic importance as an agricultural species. In the current study, the genetic variation of Japanese and English White quail ...
