Evaluation of developed low-density genotype panels for imputation to higher density in independent dairy and beef cattle populations.
The objective of this study was to develop, using alternative algorithms, low-density SNP genotyping panels (384 to 12,000 SNP), which can be accurately imputed to higher-density panels across independent cattle populations. Single nucleotide polymorphisms were selected based on genomic characteristics (i.e., linkage disequilibrium [LD], minor allele frequency [MAF], and genomic distance) in a ...
متن کاملComparison of different imputation methods from low- to high-density panels using Chinese Holstein cattle
Imputation of high-density genotypes from low- or medium-density platforms is a promising way to enhance the efficiency of whole-genome selection programs at low cost. In this study, we compared the efficiency of three widely used imputation algorithms (fastPHASE, BEAGLE and findhap) using Chinese Holstein cattle with Illumina BovineSNP50 genotypes. A total of 2108 cattle were randomly divided ...
متن کاملGenomic selection using low-density marker panels.
Genomic selection (GS) using high-density single-nucleotide polymorphisms (SNPs) is promising to improve response to selection in populations that are under artificial selection. High-density SNP genotyping of all selection candidates each generation, however, may not be cost effective. Smaller panels with SNPs that show strong associations with phenotype can be used, but this may require separ...
متن کاملAcross- and Within-breed Imputation across Several Genotyping Densities in Dairy and Beef Cattle
Illumina high density genotypes (777,962 SNPs) were available on 3,122 dairy and beef bulls. Animals were partitioned into either a calibration or validation dataset to test the accuracy of imputation. All animals, irrespective of breed, born after 2005 (n=698) were assumed to represent the validation bulls. The high density genotypes were masked in the validation animals to represent a low den...

از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...
