Transmission ratio distortion (TRD) is the departure from expected Mendelian in offspring, a poorly investigated biological phenomenon livestock species. Given current availability of specific parametric methods for analysis segregation data, this study focused on screening TRD 602 402 single nucleotide polymorphisms covering all autosomal chromosomes seven Spanish beef cattle breeds. On average, 0.13% (n = 786) and 0.01% 29) genetic markers evidenced sire- or dam-specific respectively....
The availability of SNP chips for massive genotyping has proven to be useful genetically characterize populations domestic cattle and assess their degree divergence. In this study, the Illumina BovineHD BeadChip array was used describe genetic variability divergence among 7 important autochthonous Spanish beef breeds. within-breed diversity, measured as marker expected heterozygosity, around 0.30, similar other European analysis molecular variance revealed that 94.22% total explained by...
Procedures for the detection of signatures selection can be classified according to source information they use reject null hypothesis absence selection. Three main groups tests identified that are based on: (1) analysis site frequency spectrum, (2) study extension linkage disequilibrium across length haplotypes surround polymorphism, and (3) differentiation among populations. The aim this was compare performance a subset these procedures by using dataset on seven Spanish autochthonous beef...
Abstract Epigenetics has become one of the major areas biological research. However, degree phenotypic variability that is explained by epigenetic processes still remains unclear. From a quantitative genetics perspective, estimation variance components achieved means information provided resemblance between relatives. In previous study, this was described as function component and reset coefficient indicates rate dissipation marks across generations. Given these assumptions, we propose...
Demographic and pedigree analyses describe the structure dynamics of livestock populations. We studied information recorded in herdbooks Asturiana de los Valles (AV; N = 458,806), Avileña-Negra Ibérica (ANI; 204,623), Bruna dels Pirineus (BP; 62,138), Morucha (Mo; 65,350), Pirenaica (Pi; 217,428), Retinta (Re; 135,300), Rubia Gallega (RG; 235,511) beef breeds from their creation until 2009. All have increased number registered cows recent years. In all breeds, herds do not behave as isolated...
In organisms with sexual reproduction, genetic diversity and genome evolution are governed by meiotic recombination caused crossing-over, which is known to vary within the genome. this study, we propose a simple method estimate rate that makes use of persistency linkage disequilibrium –LD- phase among closely related populations. The biological material comprised 171 triplets (sire/dam/offspring) from seven populations autochthonous beef cattle in Spain (Asturiana de los Valles,...
The Spanish local beef cattle breeds have most likely common origin followed by a process of differentiation. This particular historical evolution has probably left detectable signatures in the genome. objective this study was to identify genomic regions associated with differentiation processes seven autochthonous populations (Asturiana de los Valles (AV), Avileña-Negra Ibérica (ANI), Bruna dels Pirineus (BP), Morucha (Mo), Pirenaica (Pi), Retinta (Re) and Rubia Gallega (RG)). BovineHD 777K...
Agricultural production seeks to obtain high quality, safe products for human consumption- a great concern the dairy chain. The present investigation identify correlation between compositional and sanitary quality of raw milk (SCC/mL). was carried out in three districts Department Nariño, Colombia. For this purpose, sampling information collection executed throughout years 2016 2017. To determine relationship composition an analysis made principal components milk, design mixed models...
One of the main goals selection schemes in beef cattle populations is to increase carcass weight at slaughter. Live weights different growth stages are frequently used as criteria under hypothesis that they usually have a high and positive genetic correlation with However, presence compensatory may bias prediction ability early for purposes. Recursive models represent an interesting alternative understanding phenotypic relationship between traits during growth. For purposes this study,...
Summary This study evaluated different strategies for implementing a single‐step genomic selection programme in two autochthonous Spanish beef cattle populations (Pirenaica—Pi and Rubia Gallega— RG ). The were compared terms of accuracy attained under scenarios by simulating data over the known genealogy. Several genotyping approaches tested, as well as, other factors like marker density, effective population size, mutation rate heritability trait. results obtained showed gains with respect...
This study investigated the potential application of genomic selection under a multi-breed scheme in Spanish autochthonous beef cattle populations using simulation that replicates structure linkage disequilibrium obtained from sample 25 triplets sire/dam/offspring per population and BovineHD Beadchip. Purebred combined reference sets were used for evaluation several scenarios different genetic architecture trait investigated. The single-breed evaluations yielded highest within-breed...
El objetivo de este trabajo fue evaluar el patrón desequilibrio ligamiento a lo largo del genoma en siete poblaciones españolas autóctonas vacuno carne (Asturiana los Valles, Avileña Negra-Ibérica, Bruna dels Pirineus, Morucha, Pirenaica, Retinta y Rubia Gallega). Para ello, se utilizó BovineHD BeadChip con que genotiparon 171 tríos formados por individuo/padre/madre. Después filtrado, dispuso 573.134 SNP. A partir esta información definió un parámetro mide medio regiones 1Mb cada una las...
