Heritability of cardiovascular risk factors in a Brazilian population: Baependi Heart Study
(BIOMED CENTRAL LTDLONDON, 2008)
Background: The heritability of cardiovascular risk factors is expected to differ between populations because of the different distribution of environmental risk factors, as well as the genetic make-up of different human ...
Heritability of fear of humans in urban and rural populations of a bird species
(Nature Publishing Group, 2016-08)
Flight initiation distance (FID), a measure of an animal's tolerance to human disturbance and a descriptor of its fear of humans, is increasingly employed for conservation purposes and to predict the response of species ...
Heritability, phenotypic and genetic correlations of size and shape of Drosophila mediopunctata wings
(Nature Publishing GroupLondonInglaterra, 1999)
Genetic parameters for post-weaning visual scores and reproductive traits in Suffolk sheep
The aim of this study was to estimate the coefficients of heritability and genetic correlations among visual scores (conformation, CPW; precocity, PPW; musculature, MPW ) and reproductive traits: age at first lambing (AFL) ...
Genetic parameter estimates and principal component analysis on performance and carcass traits of a terminal pig sire line
(Taylor &francis As, 2014-07-03)
This study aimed to estimate genetic parameters for five traits related to performance and carcass in a terminal pig sire line using multitrait (MUV) and reduced rank animal models, and to analyze the relationship between ...
Genetic analysis on accumulated productivity and calving intervals in Nelore cattle
The aim of this study was to estimate genetic parameters for accumulated productivity (ACP), first calving interval (CI1), second calving interval (CI2), and mean calving interval (MCI) in Nelore beef cattle. The ACP trait ...
Estimativas de parâmetros genéticos para características morfométricas em cavalos Quarto de Milha de Corrida
With highlighted sprint ability, the racing line is important segment within the Quarter Horses breed, with huge impact on agribusiness. Theseanimals have noted morphological differences when compared to other lines within ...
Genetic parameters and relationships between heifers rebreeding and hip height in Nellore cattle
(Sociedade Brasileira de Zootecnia, 2012-03-01)
The objective of this study was to estimate heritability and verify the genetic correlations between heifers subsequent rebreeding with weaning hip height (WHH) and yearling hip height (YHH), using Bayesian inference. The ...
Genetic and environmental effects on scores of conformation, precocity and muscling in long yearling Nellore cattle
The visual scores for conformation (C), precocity (P) and muscle (M) are used to indirectly assess traits related to termination and carcass composition. This study analyzes how age of dam at calving (AC), long yearling ...
Parameter estimates for reproductive and carcass traits in Nelore beef cattle
The aim of this study was to estimate genetic parameters for scrotal circumference at 365 (SC365) and 450 (SC450) days of age, age at first calving (AFC), ribeye area (REA), backfat (BF) thickness, and rump fat (RF) ...
