genetic drift of germplasm in cultivated wheat is good motivation for studying genetic diversity in its wild relatives. in this study, r-rap, a new retrotransposon-based marker, was applied to assess the structure and genetic diversity of 30 accessions of aegilops sp. originating from different geographical regions of iran. the 15 r-rap primer combinations revealed a total of 338 bands ranging ...

The extraordinary actions of a particular father and son became a popular topic of literati writers during late-Qing times and furthermore fueled an ongoing intellectual dispute. The father, Gong Zizhen 龔自珍 (1792–1841), was a renowned scholar credited by Liang Qichao 梁啟超 (1873–1929) for having initiated the important late-Qing intellectual turn from excessive evidential research to discussions ...

Individuals who are at risk because of their family history or concerned about the possibility of having an affected child based any reasons are seeking solution approaches. Nowadays genetic counseling offers hope to prevent from suffering some genetic diseases. Advances in genetics diagnosis testing have played effective role in this regards. Interestingly, Preimplantation Genetic Testing woul...

The experiment was conducted using Randomized Complete Block Design with Row Column arrangement and three replications. Grain yield, phenological and other traits were recorded. The Residual Maximum Likelihood (REML) combined analysis of variance across locations showed very highly significant (P

The objective of the article is to investigate the variability in growth and wood properties of the willow clones. The growth and wood traits of four year old 21 clones willow clones were investigated. Analysis of variance showed that willow clones differed significantly for all the studied growth and wood traits. Among the growth parameters the maximum heritability value was shown by height wh...

Drosophila littoralis is a latitudinally widespread European species of the Drosophila virilis group. The species has ample genetic variation in photoperiodism (adult diapause) and circadian rhythmicity (pupal eclosion rhythm), with adaptive latitudinal clines in both of them. The possible common genetic basis between the variability of photoperiodism and circadian rhythms was studied by a long...

background: zoonotic cutaneous leishmaniasis (zcl) is a polymorphic disease which may show various clinical manifestations. although genetic variability of the parasite is suggested to be one of the factors influencing clinical manifestations in leishmaniasis, no data exist regarding genetic polymorphism of leishmania major . therefore, determination of genetic variation within the species of l...
