Dolapo Adepoju et al.
Background: In genetic terms, the history of a population can be described by its effective population size over time. We know that domestic cattle have gone through dramatic changes in recent history, including intensify...
Phenotypic and genetic analysis of energy partitioning and feed efficiency in Atlantic salmon [0.03%]
大西洋鲑鱼能量分配和饲料利用效率的表型和基因组分析
Anna Kristina Sonesson,Gareth Frank Difford,Ashie Norris et al.
Anna Kristina Sonesson et al.
Background: There are both economic and environmental motivations to improve feed efficiency. However, direct genetic improvement of feed efficiency ratio (FER; weight gain/feed intake) is difficult. Alternatively, improv...

Background: Closed populations are always at risk of losing genetic diversity needed for long-term genetic progress. When selecting, breeders are sometimes afraid of “missing out” on rare and/or beneficial genetic varia...

From pixels to breeding values: genetic analysis of detection and movement traits in laying hens using automated tracking data of ArUco-marked birds [0.03%]
从像素到育种值：使用ArUco标记蛋鸡的自动化跟踪数据检测和运动特征的遗传分析
T Osorio-Gallardo,A van Putten,D Janssen et al.
T Osorio-Gallardo et al.
Background: Automated tracking technologies make it possible to perform large-scale genetic analyses of behavioural traits in livestock. However, behavioural phenotypes derived from automated systems can be noisy, incompl...

Dörte Wittenburg et al.
Background: Genetic diversity among cattle breeds exists due to their demographic history and different breeding objectives for meat, dairy or dual purpose. Taking this into account, targeted breeding strategies can be fu...

Linkage- and ROH-based genomic relationship matrices for IBD based management of genetic diversity [0.03%]
基于连锁和ROH的IBD(个体间段共享系数)管理遗传多样性的基因组关系矩阵研究
Oda B Wæge,Xijiang Yu,Peer Berg et al.
Oda B Wæge et al.
Background: The goal of managing genetic diversity is to maintain both the genomic uniqueness and adaptability of a population. This entails both maintaining heterozygosity and avoiding deleterious alleles from drifting t...
Genetic analysis of iris pigmentation in Swiss pig breeds identifies a missense KITLG variant as a potential causal factor for pale and heterochromatic irises [0.03%]
瑞士猪品种虹膜色素遗传分析发现的KITLG错义突变为虹膜颜色较浅和异色虹膜的潜在原因
Wim Gorssen,Naveen Kumar Kadri,Negar Khayatzadeh et al.
Wim Gorssen et al.
Background: Iris pigmentation is a heritable trait with a complex genetic architecture. While the genetic basis of iris pigmentation has been extensively studied in humans, little is known about iris pigmentation in pigs....
Genomic estimates of Identity-By-Descent relationships in large scale data sets [0.03%]
大规模数据集中基于基因组的血缘关系估算方法
Theo Meuwisen,Xijiang Yu,Peer Berg
Theo Meuwisen
Background: Genomic relationship and inbreeding estimates are either based on genetic drift (e.g. the Genomic Relationship Matrix; GRM), homozygosity (e.g. Runs of Homozygosity; ROH), or Identity-By-Descent (IBD). A genom...
