[HTML][HTML] Genome-wide fine-mapping identifies pleiotropic and functional variants that predict many traits across global cattle populations

R Xiang, IM MacLeod, HD Daetwyler, G de Jong… - Nature …, 2021 - nature.com
The difficulty in finding causative mutations has hampered their use in genomic prediction.
Here, we present a methodology to fine-map potentially causal variants genome-wide by …

Quantifying the contribution of sequence variants with regulatory and evolutionary significance to 34 bovine complex traits

R Xiang, I Berg, IM MacLeod… - Proceedings of the …, 2019 - National Acad Sciences
Many genome variants shaping mammalian phenotype are hypothesized to regulate gene
transcription and/or to be under selection. However, most of the evidence to support this …

[HTML][HTML] Evaluation of the accuracy of imputed sequence variant genotypes and their utility for causal variant detection in cattle

H Pausch, IM MacLeod, R Fries, R Emmerling… - Genetics Selection …, 2017 - Springer
Background The availability of dense genotypes and whole-genome sequence variants
from various sources offers the opportunity to compile large datasets consisting of tens of …

Inferring demography from runs of homozygosity in whole-genome sequence, with correction for sequence errors

IM MacLeod, DM Larkin, HA Lewin… - Molecular biology …, 2013 - academic.oup.com
Whole-genome sequence is potentially the richest source of genetic data for inferring ancestral
demography. However, full sequence also presents significant challenges to fully utilize …

[HTML][HTML] New loci and neuronal pathways for resilience to heat stress in cattle

…, M Haile-Mariam, BG Cocks, IM MacLeod… - Scientific reports, 2021 - nature.com
While understanding the genetic basis of heat tolerance is crucial in the context of global
warming’s effect on humans, livestock, and wildlife, the specific genetic variants and biological …

Whole-genome resequencing of two elite sires for the detection of haplotypes under selection in dairy cattle

…, J Thimmapuram, IM Macleod… - Proceedings of the …, 2012 - National Acad Sciences
Using a combination of whole-genome resequencing and high-density genotyping arrays,
genome-wide haplotypes were reconstructed for two of the most important bulls in the history …

[HTML][HTML] Population structure and history of the Welsh sheep breeds determined by whole genome genotyping

…, B Davies, W Haresign, J Kijas, IM MacLeod… - BMC genetics, 2015 - Springer
Background One of the most economically important areas within the Welsh agricultural
sector is sheep farming, contributing around £230 million to the UK economy annually. …

[HTML][HTML] Genomic prediction based on selected variants from imputed whole-genome sequence data in Australian sheep populations

…, AA Swan, HD Daetwyler, IM MacLeod - Genetics Selection …, 2019 - Springer
Background Whole-genome sequence (WGS) data could contain information on genetic
variants at or in high linkage disequilibrium with causative mutations that underlie the genetic …

The effects of demography and long-term selection on the accuracy of genomic prediction with sequence data

IM MacLeod, BJ Hayes, ME Goddard - Genetics, 2014 - academic.oup.com
The use of dense SNPs to predict the genetic value of an individual for a complex trait is
often referred to as “genomic selection” in livestock and crops, but is also relevant to human …

[HTML][HTML] In it for the long run: perspectives on exploiting long-read sequencing in livestock for population scale studies of structural variants

…, BJ Hayes, AJ Chamberlain, IM MacLeod - Genetics Selection …, 2023 - Springer
Studies have demonstrated that structural variants (SV) play a substantial role in the evolution
of species and have an impact on Mendelian traits in the genome. However, unlike small …
