Abstract We present here a simple approach to obtain reliable estimates of the effective population size in real world populations via computation increase inbreeding for each individual (delta F i ) given population. The values delta are computed as t -root 1 - (1 where is coefficient and equivalent complete generations individual. pre-defined reference subset can be averaged used estimate size. A standard error this N e further from deviation inbreeding. methodology demonstrated by...
We introduce a simple method to estimate effective population size from increase in coancestry (Δc(jk)) for all pairs of individuals j and k reference subpopulation. An pairwise any pair can be defined assuming that hypothetical mating between them would give an individual with inbreeding coefficient equal c(jk), where c(jk) is the k. The equivalent measure discrete generations value (g(jk)) corresponding jk computed by averaging equivalents its parents (g(j) g(k)). mean subpopulation used...
Summary The objective of this study was to test the performance a recently proposed methodology for estimation realized effective size ( N e ) based on individual increase in inbreeding ΔF i several real pedigrees: (a) an experimental mice population; (b) closed pedigree fighting bulls; (c) Spanish Purebred (SPB, Andalusian) horse pedigree; (d) Carthusian strain SPB (e) Arab and (f) Anglo‐Arab pedigree. Several reference subpopulations were defined basis generation length order consider only...
The aims of this study were, first, to evaluate eye temperature (ET) with infrared thermography and heart rate (HR) measure stress in horses during show jumping competitions their relationship competition results, second, the influence different extrinsic intrinsic factors horse on measurements analysed. One hundred seventy-three Spanish Sport Horses were analysed for ET HR, these taken 3 h before competition, just after it. Two interval also assessed each parameter. Positive significant...
The main goal of the current work was to infer demographic history seven Spanish goat breeds (Malagueña, Murciano-Granadina, Florida, Palmera, Mallorquina, Bermeya and Blanca de Rasquera) based on genome-wide diversity data generated with Illumina Goat SNP50 BeadChip (population size, N = 176). Five additional populations from Europe (Saanen Carpathian) Africa (Tunisian, Djallonké Sahel) were also included in this analysis (N 80) for comparative purposes. Our results show that genetic...
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 objective of the present study was to assess frequency distribution markers in diacylglycerol acyltransferase (DGAT1), fatty acid binding protein 4 (FABP4), leptin (LEP), retinoic receptor-related orphan receptor C (RORC), and stearoyl-CoA desaturase (SCD1) genes a Spanish commercial crossbred population (n = 286) produced southwest Spain. We have also evaluated association these 5 major SNP with backfat thickness (BFT) intramuscular fat (IMF) use them routinely industry (if associations...
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...
Since their domestication 10,500 years ago, goat populations with distinctive genetic backgrounds have adapted to a broad variety of environments and breeding conditions. The VarGoats project is an international 1000-genome resequencing program designed understand the consequences on diversity domestic goats elucidate how speciation hybridization modeled genomes set species representative genus Capra.A dataset comprising 652 sequenced 507 public sequences, including 35 animals representing...
Background: The single-step best linear unbiased predictor (ssGBLUP) has emerged as a reference method for genomic selection in recent years due to its advantages over traditional approaches. Although application horses remains limited, ssGBLUP demonstrated the potential improve reliability of estimated breeding values livestock species. This study aimed assess impact incorporating data using restricted maximum likelihood (ssGREML) on (R2) Pura Raza Española (PRE) horse breed, compared...
Litter size records from two lines of Tunisian Barbarine sheep were analysed across parities using an RRM.

ABSTRACT Most Parid species produce specific, order‐constrained mobbing calls. These calls elicit responses from both conspecifics and heterospecifics, with evidence indicating that such occur only when the are organised in this specific order. One notable exception is coal tit ( Periparus ater ), a employs similar types of notes, yet does not exhibit clear order constraints within its sequences. Despite apparent absence constraints, recent experiment has demonstrated tits may be sensitive...
Despite a number of recent studies that have focused on the origin domestic horses, genetic relationships between major geographical clusters still remain poorly understood. In this study we analyzed 296 bp mtDNA fragment from HVI region 171 horses representing 11 native Iberian, Barb, and Exmoor breeds to assess maternal phylogeography Iberian horses. The haplogroup with CCG motif (nucleotide position 15,494 15,496) was most frequent in Barb (0.42 0.57, respectively), regardless geographic...
Abstract Mitochondrial DNA diversity was analysed in 19 Iberian and six foreign sheep breeds. Three mtDNA lineages (B, A C) were found the sheep, with type B clearly predominating over others. The results for each of morphologically determined breed groups sheep: Merino , Entrefino Churro trunks. MtDNA lineage C only trunk composed Montesina Ojalada. These two populations had high variability, Branco more variation. other three types studied showed moderate including most authentic Spanish...
