the objective of this study was to estimate variance components, genetic and phenotypic trends for somatic cell score. dataset that collected by the animal breeding center of iran was used in this study. data file included 850,729 test day records of somatic cell counts (scc)  on 32,955 cows from lactations one to four, in 472 herds, gathered from years 2002 to 2013 in iran. a test day repeatab...

genetic parameters and trends for milk and fat yields as well as for fat percentage were estimated from 35,438 milk production records (305d, 2x) of 17,971 holstein dairy cattle in 133 herds during the period of 1990-2003 in khorasan province. variance components were estimated using restricted maximum likelihood statistical method applying univariate and repeatability animal models. for the un...

Autosomal dominant polycystic kidney disease (ADPKD) is the most common genetic nephropathy, which is characterized by replacement of renal parenchyma with multiple cysts. In Iran, the disease prevalence within the chronic hemodialysis patient population is approximately 8-10%. So far, three genetic loci have been identified to be responsible for ADPKD. Little information is available concernin...

more often patients refer for genetic counseling, without definite diagnosis. mostly people and some doctor! have the impression the all muscular dystrophy affected by boys but is carried by girles. more often review of medical history of theses patients resolved this finding different clinical (neurologists), physiotherapist (ncv,emg) and pathologists diagnosis and also negative result molecul...

Human intraspecific variation is a complex problem, but may be better understood by using computational models in tandem with knowledge about the genetic bases of phenotypic traits. These results can be used in a multitude of settings. To move closer to this goal, biologically-realistic mappings between genotype and phenotype are constructed using genetic algorithm and neural network-like model...
