Abstract:
Abstract Estimation of genetic parameters for carcass traits and their use in the evaluation of carcass quality is of considerable importance in the genetic improvement of beef cattle. The objective of this study was to compare the predictive ability of single- and multi-trait genomic prediction models for the following carcass quality traits: hot carcass weight (HCW); fat thickness (FAT); rib eye area (REA); marbling score (MARB); and peak force (PEAKF) from multibreed and purebred populations.

Genetic correlations between longevity and conformation traits were estimated using data on Czech Holstein cows first calved in the years 1993–2008. Longevity traits considered were length of productive life and number of lactations initiated and their functional equivalents (i.e. the longevity traits corrected for milk production). Conformation traits were twenty one linear descriptive type traits, six composite traits and height at sacrum measured in cm. A possible nonlinear relationship between conformation and longevity traits was also investigated. The heritabilities ranged from

Abstract Mapping quantitative trait loci (QTL) for complex binary traits is more challenging than for normally distributed traits due to the nonlinear relationship between the observed phenotype and unobservable genetic effects, especially when the mapping population contains multiple outbred families. Because the number of alleles of a QTL depends on the number of founders in an outbred population, it is more appropriate to treat the effect of each allele as a random variable so that a single variance rather than individual allelic effects is estimated and tested.

Abstract:
Dissection of quantitative traits to the nucleotide level requires phenotypic and genotypic analysis of traits on a genome scale. Here we discuss the set of community-wide genetic and molecular resources, including panels of specific types of inbred lines and high density resequencing and SNP detection, that will facilitate such studies.

Abstract:
Abstract Heritable variation in polygenic (quantitative) traits is critical for adaptive evolution and is especially important in this era of rapid climate change. In this study, we examined the levels of quantitative genetic variation of populations of the tropical tree Quercus oleoides Cham. and Schlect. for a suite of traits related to resource use and drought resistance. We tested whether quantitative genetic variation differed across traits, populations and watering treatments. We also tested potential evolutionary factors that might have shaped such a pattern: selection by climate and ge

This study treats a comparative analysis of local differentiation of Albanian bee population according to 12 front wing traits and 18 other traits. To conduct this study, were used evaluations for the averages of these morphological traits measured in 3600 honey bees, in 60 different regions, scattered in all the place territory. The measurement of 30 traits was done using Scan Photo Technique (SPT). Local differentiation that was obtained in Albanian bee population by its front wing traits is not great. This differentiation does not explain by the phenomenon of isolation in distance. Human in

Abstract:
Two geographically distinct populations of the submerged aquatic macrophyte Ceratophyllum demersum L. were compared after acclimation to five different nitrogen concentrations (0.005, 0.02, 0.05, 0.1 and 0.2 mM N) in a common garden setup. The two populations were an apparent invasive population from New Zealand (NZ) and a noninvasive population from Denmark (DK). The populations were compared with a focus on both morphological and physiological traits. The NZ population had higher relative growth rates (RGRs) and photosynthesis rates (Pmax) (range: RGR, 0.06–0.08 per day; Pmax, 200–395 µmol O

Abstract:
Fisher's theorem of natural selection implies that the population genetic variance of quasi-neutral traits should be mostly additive. In the case of fitness component traits, however, that variance would be characterised by a substantial contribution from non-additive loci. In parallel, Robertson's theorem states that selection will change the population mean of a trait proportionally to the magnitude of the genetic correlation between that trait and fitness, which should be weak for quasi-neutral traits or strong for the mean fitness components.

<b>Background and aims</b> – Habitat fragmentation may compromise population survival and decrease the ability to face environmental changes. Small and isolated populations in particular may suffer from disrupted pollination processes. However, a species' response to fragmentation may vary according to life history traits. Understanding how pollen dispersal is shaped by population and life history traits such as mating system and clonal growth is therefore essential for assessing species' response to fragmentation. <b>Methods</b> – We investigated pollen dispersal using fluorescent dyes in nin

Abstract:
Defensive traits exhibited by plants vary widely across populations. Heritable phenotypic differentiation is likely to be produced by genetic drift and spatially restricted gene flow between populations. However, spatially variable selection exerted by herbivores may also give rise to differences among populations. To explore to what extent these factors promote the among-population differentiation of plant resistance of 13 populations ofDatura stramonium, we compared the degree of phenotypic differentiation (PST) of leaf resistance traits (trichome density, atropine and scopolamine concentrat
