Estimating inbreeding depression for growth and reproductive traits using pedigree and genomic methods in Argentinean Brangus cattle
(American Society of Animal Science, 2021-11)
Inbreeding depression reduces the mean phenotypic value of important traits in livestock populations. The goal of this work was to estimate the level of inbreeding and inbreeding depression for growth and reproductive ...
Estimates of autozygosity through runs of homozygosity in farmed coho salmon
(MDPI, 2020)
The characterization of runs of homozygosity (ROH), using high-density single nucleotide polymorphisms (SNPs) allows inferences to be made about the past demographic history of animal populations and the genomic ROH has ...
Assessment of runs of homozygosity islands and estimates of genomic inbreeding in Gyr (Bos indicus) dairy cattle
(2018-01-09)
Background: Runs of homozygosity (ROH) are continuous homozygous segments of the DNA sequence. They have been applied to quantify individual autozygosity and used as a potential inbreeding measure in livestock species. The ...
Analysis of the Pedigree and Ancestors of the Cutting Population of the Quarter Horse Breed
(2021-04-01)
The aim of this study was to evaluate the genetic diversity and to identify the most influential ancestors in the population of Brazilian Quarter Horses participating in cutting competitions. Data from 1,590 elite horses ...
Preliminary study to determine extent of linkage disequilibrium and estimates of autozygosity in Brazilian Gyr dairy cattleEstudo preliminar sobre a extensão do desequilíbrio de ligação e estimativas de autozigose em bovinos leiteiros da raça Gir
(2015-01-01)
Genotypes of 25 artificial insemination sires were used to study the extent of linkage disequilibrium (LD) and the correspondence between pedigree and SNP-based estimators of inbreeding in Brazilian Gyr dairy cattle. ...
Autozygosity islands and ROH patterns in Nellore lineages: Evidence of selection for functionally important traits 06 Biological Sciences 0604 Genetics
(2018-09-17)
Background: The aim of this study was to assess genome-wide autozygosity in a Nellore cattle population and to characterize ROH patterns and autozygosity islands that may have occurred due to selection within its lineages. ...
Pedigree analysis of the racing line Quarter Horse: Genetic diversity and most influential ancestors
(2021-05-01)
The aims of this study were to evaluate the genetic diversity of the racing line Quarter Horse breed in Brazil and to provide data on the most influential ancestors by pedigree analysis. All horses that had participated ...
Assessment of pedigree information in the Quarter Horse: Population, breeding and genetic diversity
(2018-08-01)
This study aimed to evaluate population parameters and to describe the genetic diversity of Quarter Horse breed (QH) in Brazil, reported for the first time in the literature. The pedigree data comprised 131,716 animals ...
Estrutura genômica de uma população de suínos base Landrace
(Universidade Estadual Paulista (Unesp), 2016-02-22)
Os painéis de marcadores de alta densidade têm demonstrado a sua funcionalidade nos estudos de estrutura da população e conservação genética. Esses painéis permitem avaliar similaridades no padrão do desequilíbrio de ...
Variabilidade genética da raça Brahman no Brasil detectada por meio de análise de pedigree
(Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), 2010-10-01)
O objetivo deste trabalho foi analisar a variabilidade genética da raça Brahman no Brasil, por meio da análise de 15.851 pedigrees. O arquivo de dados foi dividido em dois períodos: 1998-2001 e 2002-2005. A variabilidade ...
