Genomic prediction using a reference population of multiple pure breeds and admixed individuals

Genetics Selection Evolution, 2021
Background In dairy cattle populations in which crossbreeding has been used, animals show some level of diversity in their origins. In rotational crossbreeding, for instance, crossbred dams are mated with purebred sires from different pure breeds, and ...

The impact of genotyping strategies and statistical models on accuracy of genomic prediction for survival in pigs

Journal of Animal Science and Biotechnology, 2023
Background Survival from birth to slaughter is an important economic trait in commercial pig productions. Increasing survival can improve both economic efficiency and animal welfare. The aim of this study is to explore the impact of genotyping strategies

QUANTITATIVE GENETICS OF HETEROCHRONY [PDF]

Evolution, 1987
A model of quantitative-genetic variation in developmental processes is introduced and analyzed. The model is of a bifurcating sequence of events in which traits develop from the same tissue until a transition occurs, after which they develop partially independently.

Transcriptomic and presence/absence variation in the barley genome assessed from multi-tissue mRNA sequencing and their power to predict phenotypic traits

BMC Genomics, 2019
Background Barley is the world’s fourth most cultivated cereal and is an important crop model for genetic studies. One layer of genomic information that remains poorly explored in barley is presence/absence variation (PAV), which has been suggested to ...

Effective Selection for Lower Mortality in Organic Pigs through Selection for Total Number Born and Number of Dead Piglets

Animals, 2022
Selection for the number of living pigs on day 11 (L11) aims to reduce piglet mortality and increase litter size simultaneously. This approach could be sub-optimal, especially for organic pig breeding.

Quantitative Genetics and Population Dynamics [PDF]

Evolution, 1996
This study examines the dynamics of a competition and a host-parasite model in which the interactions are determined by quantitative characters. Both models are extensions of one-dimensional difference equations that can exhibit complicated dynamics. Compared to these basic models, the phenotypic variability given by the quantitative characters reduces

Genomic prediction in Nordic Red dairy cattle considering breed origin of alleles

Journal of Dairy Science, 2022
: This study investigated the reliability of genomic prediction (GP) using breed origin of alleles (BOA) approach in the Nordic Red (RDC) population, which has an admixed population structure.

Prioritizing candidate genes post-GWAS using multiple sources of data for mastitis resistance in dairy cattle

BMC Genomics, 2018
Background Improving resistance to mastitis, one of the costliest diseases in dairy production, has become an important objective in dairy cattle breeding. However, mastitis resistance is influenced by many genes involved in multiple processes, including

Dissecting closely linked association signals in combination with the mammalian phenotype database can identify candidate genes in dairy cattle

BMC Genetics, 2019
Background Genome-wide association studies (GWAS) have been successfully implemented in cattle research and breeding. However, moving from the associations to identify the causal variants and reveal underlying mechanisms have proven complicated. In dairy
