Study of diversity and morphometric differentiation of of Garra rufa (Heckel, 1843) populations in Fars province
This investigation was conducted to study of diversity and distinction of Garra rufa in some aquatic ecosystems located in Fars province. So, 208 samples were collected from five aquatic ecosystems located in Fars province (Rudbal river, Babasheikh Khalil subterranean, Qaderabad subterranean, Doudabad subterranean, Khargheh river) and 24 morphological traits were measured. Before data analysis,...
متن کاملGenetic differentiation of Jewish populations.
The Jewish diaspora can be viewed as a natural process in population dispersion and differentiation. We extend genetic studies on the Jewish diaspora to an analysis of human leukocyte antigen (HLA) haplotype distributions in the Jewish peoples, and show the value of this information for the design of Jewish marrow donor registries. HLA data from the Hadassah Bone Marrow Registry having parental...
متن کاملPhysiological Differentiation of Vertebrate Populations
INTRODUCTlON ,. . The foundation of most evolutionary theory rests upon inferences drawn from geographic variation or upon the verification of predictions made about it. The study of geographic variation occupies a central position in evolutionary biology. .. because geographic variation is ordinarily the smallest amount of evolution that can be detected in nature and because evolutionary theor...
متن کاملTesting differentiation in diploid populations.
We examine the power of different exact tests of differentiation for diploid populations. Since there is not necessarily random mating within populations, the appropriate hypothesis to construct exact tests is that of independent sampling of genotypes. There are two categories of tests, FST-estimator tests and goodness of fit tests. In this latter category, we distinguish "allelic statistics", ...
متن کاملBayesian analysis of genetic differentiation between populations.
We introduce a Bayesian method for estimating hidden population substructure using multilocus molecular markers and geographical information provided by the sampling design. The joint posterior distribution of the substructure and allele frequencies of the respective populations is available in an analytical form when the number of populations is small, whereas an approximation based on a Marko...
