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...
Largemouth bass (Micropterus salmoides) is an economically important species in China. Contrary to its rapidly increasing yield during the last decades, domestic genetic diversity of largemouth has gradually declined. In this study, 37 single nucleotide polymorphism (SNP) markers were developed based on genotyping-by-sequencing data and characterized by genotyping 32 individuals using PCR–restr...
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...
To empirically determine the effects of sample size on commonly used measures of average genetic diversity, we genotyped 200 song sparrows Melospiza melodia from two populations, one genetically depauperate (n 100) and the other genetically diverse (n 100), using eight microsatellite loci. These genotypes were used to randomly create 10,000 datasets of differing sizes (5 to 50) for each populat...
Coltman and Slate (2003) recently performed a meta-analysis on studies that investigated the association between genetic variation at microsatellite loci and phenotypic trait variation. One factor not explicitly addressed in their meta-analysis is the actual estimation of genome-wide heterozygosity via molecular markers. Many authors still associate marker-estimated heterozygosity with genome-w...
Hemophilia B, an X-linked recessive bleeding disorder, is caused by heterogeneous mutations in the factor IX (F9) gene. Hence, carriers of the disease are usually detected by F9 gene linked RFLP analysis. We aimed to test a set of RFLP markers (DdeI, XmnI, MnlI, TaqI & HhaI), used worldwide for carrier detection, to estimate its heterozygosity in different population groups of India, and identi...
Population genetic structure of stellate sturgeon (Acipenser stellatus) in 197 adult specimens from four fishery regions along the Iranian coastline of the southern Caspian Sea was investigated using microsatellite markers. Out of 15 microsatellite primers, 11 loci were produced, in which 10 of them were polymorphic and 1 was monomorph. Totally, 184 alleles were identified and on average 13.1 a...
The orangeback flying squid, Sthenoteuthis pteropus, is a species of significant potential value that widely distributed in the tropical and temperate waters Atlantic Ocean. There have been no reports population genetics effective molecular markers for this due to lack reliable information regarding its genetic structure many individual differences, as well complex changeable life history. Ther...
We explored genetic variation by sequencing a selection of 84 tomato accessions and related wild species representative of the Lycopersicon, Arcanum, Eriopersicon and Neolycopersicon groups, which has yielded a huge amount of precious data on sequence diversity in the tomato clade. Three new reference genomes were reconstructed to support our comparative genome analyses. Comparative sequence al...
