Genome-wide association study of milk and reproductive traits in dual-purpose Xinjiang Brown cattle

tailieu.vn

Therefore, GWAS with high-density SNPs are needed to understand the genetic architecture of important, complex traits in dual-purpose cattle breeds.. and one health trait: somatic cell score (SCS) in the Chinese dual-purpose cattle breed, Xinjiang Brown. Our objective was to identify SNPs associated with milk, reproductive, and health traits in the Xinjiang Brown for the benefit of marker-assisted selection and dissection of genetic archi- tecture of these complex traits..

GWAS and fine-mapping of livability and six disease traits in Holstein cattle

tailieu.vn

Genome-wide association studies (GWAS) have been successful at interrogating the genetic basis of complex traits and diseases in cattle [7–10]. Addition- ally, this method can be exploited to identify biologically meaningful information from candidate genes to enhance the understanding of complex traits [15].. Cow livability was included in the national genomic evaluation system by the Council on Dairy Cattle Breeding (CDCB) in 2016 [16].

Genome-wide association studies for yield component traits in a macadamia breeding population

tailieu.vn

The use of genomics in plant breeding is expand- ing [4–6], including employing genome-wide associ- ation studies to identify molecular markers associated with important traits, and genomic selec- tion for complex traits. A common approach is using genome-wide association studies (GWAS): each marker (typically single nucleotide polymorphism, SNP) is tested individually to detect evidence of marker-trait associations [4].

A whole genome sequence variant panel represents the ultimate DNA marker set to dissect genetic controls of complex traits via genetic analyses including genome wide association studies as whole genome sequence vari- ants contain all causative polymorphisms that contribute to the variation of the trait.

Analyses of inter-individual variations of sperm DNA methylation and their potential implications in cattle

tailieu.vn

HVMRs were associated with QTLs of reproduction traits To explore the relationship between HVMRs in sperm and complex traits, we first examined the QTL regions of six categories of traits (n = 232) (Exterior, health, Meat, milk, production and reproduction traits) from the Cattle QTL database (https://www.animalgenome.. While hyper-CMRs were highly associated with a range of complex traits such as milk production traits, non- return rate and calving ease (CE) (Fig.

A fast-linear mixed model for genome-wide haplotype association analysis: Application to agronomic traits in maize

tailieu.vn

Genome-wide association analysis for large genetic units shows major advantages over SNPs in relation to: 1). explaining large percentages of phenotype variations by the combined effects of multiple SNPs and 2) facilitating the study of mechanisms related to complex traits by biologically meaningful genetic units such as genes and pathways [9]..

Trait differentiation and modular toxin expression in palm-pitvipers

tailieu.vn

Our understanding of the selective forces that generate modularity and how modularity in turn medi- ates and facilitates the evolution of complex traits remains incomplete. However, as we have shown here, on-going efforts to address these questions in dynamic adaptive systems can provide key insights that lead to a more inte- grated understanding of the genomics of rapid adaptation in complex traits..

Performances of Adaptive MultiBLUP, Bayesian regressions, and weighted-GBLUP approaches for genomic predictions in Belgian Blue beef cattle

tailieu.vn

The objective of the present study was to apply the AM- BLUP method for genomic predictions of complex traits in BBB cattle in order to study its properties in a live- stock population. To do so, we compared the approach to state-of-the-art methods as GBLUP or BSLMM. Regions and SNPs significantly associated with traits Application of the AM-BLUP results in the identification of regions significantly associated with each trait and consequently provides information on their genetic architecture.

Container-aided integrative QTL and RNAseq analysis of Collaborative Cross mice supports distinct sex-oriented molecular modes of response in obesity

tailieu.vn

The CC panel is an experimental population that aids with the dissection of the genetic mechanisms underlying sus- ceptibility to complex traits, such as obesity. Chromo- somal regions that are involved in the susceptibility or resistance to the trait can be mapped as quantitative trait loci (QTL) with high precision.

Genome-wide association analysis reveals genetic variations and candidate genes associated with salt tolerance related traits in Gossypium hirsutum

In this study, the population panel consisted of 217 cultivars from differ- ent ecological regions (the Yellow River, the Yangtze River, the Northwestern inland region, the Northern China region, America and Australia) Phenotypic ana- lysis showed that the salt tolerance related traits in two. Recent years, association mapping as an important method for the identification of complex quantitative traits has been widely used in cotton for various traits including salt tolerance [35–40].

According to Wattoo et al., (2010), grain yield is a complex trait that depends upon different yield attributing traits.. The present study was therefore undertaken to study the clustering pattern and correlation in aromatic rice landraces for yield attributing traits..
