Linkage disequilibrium was estimated using 7119 single nucleotide polymorphism markers across the genome and 200 animals from North American Holstein cattle population. The analysis of maternally inherited haplotypes revealed strong linkage (r(2) > 0.8) in genomic regions approximately 50 kb or less. While decays as a function distance, within genes showed greater variation compared with intergenic regions. Identification haplotype blocks could characterize most common haplotypes. Although...
Summary In this study, to identify genomic signatures of divergent selection, we genotyped 10 cattle breeds/populations ( n = 275), representing eight Ethiopian populations 229) and two zebu 46) adapted tropical sub‐tropical environments, using the high‐density single‐nucleotide polymorphisms (SNPs) derived mainly from Bos indicus breeds, five reference taurine breeds 212). Population genetic differentiation F ST ) values across sliding windows were estimated between combined breeds. The...
The development of high throughput genotyping techniques has facilitated the identification selection signatures pigs. detection genomic signals in a population subjected to differential pressures may provide insights into genes associated with economically and biologically important traits. To identify regions under selection, we genotyped 488 Duroc (D) pigs 155 D × Korean native (DKNPs) using Porcine SNP70K BeadChip. By applying FST extended haplotype homozygosity (EHH-Rsb) methods,...
Summary DNA markers associated with quantitative trait loci ( QTL ) affecting host tolerance to gastrointestinal GI parasite infection are ideal targets for marker‐assisted selection. However, few studies in cattle have attempted identify this type of due the difficulty generating accurate phenotypic data from a resource population adequate statistical power detection. For effort, we amassed fecal egg count FEC measures annual natural field challenges nematodes that spanned 12 different...
c-MYC (v-myelocytomatosis viral oncogene homologue) is a transcription factor that plays important role in many biological process including cell growth and differentiation, such as myogenesis adipogenesis. In this study, we aimed to detect MYC gene polymorphisms, their genotype frequencies determine associations between these polymorphisms meat quality traits Berkshire pigs. We identified single nucleotide polymorphism (SNP) intron 2 of by Sanger sequencing, i.e., g.3350G>C (rs321898326),...
Duroc breed is known for its superior performance in terms of growth, carcass and meat quality traits. The imported into South Korea commercial production has been under selection economic traits during the last decades. However, signatures Korean populations have not yet investigated at genome level. In this study, we detected four (n = 488) crossbred pigs (Duroc × native pig, n 155) sampled from five pig farms genotyped using 50,862 autosomal markers. By applying FST extended haplotype...
