In order to have a good perspective of wild animals, it is necessary to determine their population and genetic structure. It provides an opportunity to decide on better conservation managements. In the wilderness, due to the escapable nature and sometimes not having the distinguishable bisexual appearance, sex identification could be difficult by observing animals. The X- and Y- chromosome link...
The Japanese threadfin bream, Nemipterus japonicus, the most abundant and crucially economic Nemipterus species is widespread throughout the Indo-West Pacific. The species has been studied widely for various aspects but genetic studies are scanty. This preliminary study contributes to the species phylogeography through the study of the genetic diversity and historical demography of N. japonicus...
Chickpea (Cicer arietnum) as the third most important grain legume in the world is not only an important source of feed but it also improve soil fertility by adding nitrogen. This work was aimed to study the variability of morphological trait, to estimate PCV, GCV, heritability, and expected genetic advance of quantitative traits of Chickpea. The genotypes were planted in a randomized complete ...
In modern programmes of animal breeding, the polymorphisms of the milk proteins can be used as marker systems. Beta-Lactoglobulin is the major milk whey protein in the ruminants. The BLG coding gene located on ovine chromosome 3. This protein, synthesis in the mammary glands during pregnancy and the lactation stages. Studies have indicated that this protein is polymorphic in the many breeds of ...
The aim of present study was to compare levels of genetic polymorphism between offspring of wild , farmed and mix of them of Roach (Rurilus rutilus caspicus) using five microsatellite loci (CA1, CA7, CypG27, Lid1, Rru4). Genetic diversity was investigated by studying samples collected from three population, 90 fish, thirty specimen form each population. All samples fixed in ethanol 96% until ...
rapd markers were employed to assess the genetic diversity of 34 iranian wild edible asparagus (a. officinalis) genotypes as well as cv. mary washington and a. persicus. in total, 80 rapd primers were employed for pcr reactions, among which, 18 revealed reasonable polymorphism. the 18 primers produced 175 bands, of which, 160 were polymorphic (91.4% polymorphism). cluster analysis of the genoty...

We look at how to choose genetic distance so as to maximize the power of detecting spatial structure. We answer this question through analyzing two population genetic models that allow for a spatially structured population in a continuous habitat. These models, like most that incorporate spatial structure, can be characterized by a separation of timescales: the history of the sample can be spli...
