In the present study two genetically connected small and large populations were simulated and the effect of different sources of information from foreign populations on the accuracy of predicted genomic breeding values of young animals of the small population was investigated. A large population consist of 200000 animals over 15 generations and a small population consist of 5000 animals over 3 ...

In this research, investigation of genetic, phenotypic and environmental trends of biometric traits in Makuie sheep was performed using collected data from 1989 to 2012 at Makouei sheep breeding station. Estimation of trends was performed by multivariate animal model using the DFREML software. Genetic, phenotypic and environmental trends were estimated by regression of breeding values average, ...

with the introduction of communicative language teaching, a large number of studies have concerned with students’ oral participation in language classrooms. although the importance of classroom participation is evident, some language learners are unwilling to engage in oral activities. this passivity and unwillingness to participate in language classroom discussions is known as “reticence”. rev...

In this study, 5608 records of Kordi sheep body weights collected during 21 years (1990 to 2010) in Sheep Breeding Station of Shirvan were used to estimate genetic, phenotypic and environmental trends. Best linear unbiased predictions (BLUP) of breeding values were obtained by derivative free restricted maximum likelihood (DFREML) using univariate animal model. Genetic, phenotypic and environme...

To investigate the effects of categorical trait levels on EBVs accuracies, genetic and phenotypic trends and inbreeding coefficient, a breeding stock contained 400 animals was simulated through stochastic method using R programming package. The population was simulated for 7 generations while each generation contained 200 animals. The generations were overlapped and in each ones 20 percent of t...

One of the most complicated issues in plant breeding programs is genotype by environment interaction. To evaluate seed yield stability of 18 chickpea promising lines, a field experiment was conducted using randomized complete block design with four replications in two cropping seasons (2018-19 and 2019-2020) in four research stations (Maragheh, Kurdistan West Azerbaijan and Hamedan), Iran.
