in poland the conservation program of atlantic sturgeon acipenser oxyrinchus is conducted during over 10 years by inland fisheries institute in olsztyn, poland. material of a. oxyrinchus is annually transported from canada to poland and the broodstock of this species is created. part of imported fish material is breed and released into local rivers e.g. drweca river, vistula river. all the impo...

background & aim: german chamomile is one of the most important medicinal plants. so, assessment of genetic diversity and relationship among the traits are very essential in chamomile breeding programs. determination of the best indirect selection criteria for genetic improvement of essence percent and dry flower yield of german chamomile (matricaria chamomilla l.) populations was investiga...

BACKGROUND Little is known about family members' interrelated decisions to seek genetic testing for breast cancer susceptibility. METHODS The specific aims of this cross-sectional, descriptive, cohort study were (i) to examine whether individual and family characteristics have a direct effect on women's decisions to use genetic testing for hereditary susceptibility to breast cancer and (ii) t...

axial flux permanent magnet (afpm) machines are attractive candidates for electric vehicles (evs) applications due to their axial compact structure, high efficiency, high power and torque density. this paper presents general design characteristics of afpm machines. moreover, torque density of the machine which is selected as main objective function, is enhanced by using genetic algorithm (ga) a...

Recently, a quantitative-trait locus (QTL) for whole blood serotonin level was identified in a genomewide linkage and association study in a founder population. Because serotonin level is a sexually dimorphic trait, in the present study, we evaluated the sex-specific genetic architecture of whole blood serotonin level in the same population. Here, we use an extended homozygosity-by-descent link...

Many species exhibit sexual dimorphism in a variety of characters, and the underlying genetic architecture of dimorphism potentially involves sex-specific differences in the additive-genetic variance-covariance matrix (G) of dimorphic traits. We investigated the quantitative-genetic structure of dimorphic traits in the dioecious plant Silene latifolia by estimating G (including within-sex matri...

HE formal genetics of flour beetles of the genus Tribolium is still in its infancy. Although these organisms have found a habitat in the laboratories of the ecologist, the quantitative geneticist, and more recently, the population biologist (KING and DAWSON 1972) their use has been restricted by the availability of only a limited number of reliable mutants and further hampered by a meager knowl...

to study general and specific combining ability of some rice varieties for grain physical properties and milling quality, a diallel design with five parents (hashemi, vandana, kadous, shahpasand and ir36) was used. parents and their f1 progenies (25 genotypes) were grown in a randomized complete blocks design with three replications in the research field of rice research institute of iran (rrii...

This present study investigated the genetic and environmental influences on the associations between adolescents' peer characteristics (i.e., peer college orientation, and peer delinquency) and smoking in young adulthood. We used longitudinal data from the Nonshared Environment and Adolescent Development (NEAD) project. Parents' reports on adolescents' peer characteristics and adolescents' self...
