- the discovery of the genetic determinants of the traits : additivity, dominance, overdominance for the direct and maternal genetic effects. - the study of the theoretical efficiency of selection methods which can be used . In this paper, rather than focusing on genes as an organising concept around which historical considerations of theory and practice in genetics are elucidated, we place genetic markers at the heart of our analysis. Other widely used imputation methods in genetics, such as that implemented in MaCH (Li et al. 2010), could not be used because of the lack of precise mapping information at the time of the analysis; a 90K consensus map has just been… The analysis and inferences of Hill et al. (2008) took into account the size and direction of interaction effects and the allele frequencies or heterozygosity at all contributing loci. We investigated the genetic and statistical properties of the nested association mapping (NAM) design currently being implemented in maize (26 diverse founders and 5000 distinct immortal genotypes) to dissect the genetic basis of complex…

What's required is linkage disequilibrium between a QTL and a marker (since, if the traits were in Hardy-Weinberg, there would be no association between a marker genotype and a QTL genotype), which is maximized in inbred strains but can… traits behave according to the model of monogenic or simple gene inheritance in which one gene corresponds to one trait. Discrete traits (as opposed to continuously varying traits such as height) with simple Mendelian inheritance patterns… The year 1900 marked the "rediscovery of Mendel" by Hugo de Vries, Carl Correns and Erich von Tschermak, and by 1915 the basic principles of Mendelian genetics had been studied in a wide variety of organisms — most notably the fruit fly… Recent application of broad-spectrum metabolite profiling to the study of natural variation and quantitative genetics has provided unique insights into the basic underpinnings of plant genetics.

The two types of approaches lead to predictions of genomic values for quantitative traits. An advantage of explicitly regressing phenotypes on marker covariates is that the model can produce information about genomic regions that may affect…
Corolla width and projected area of the corolla were determined by analysis (NIH Image; http://rsb.info.nih.gov/nih-image) of video images of whole flowers taken in a plane perpendicular to the long axis of the corolla tube, which… As a result, there is a large discrepancy between the known heritability of most traits and the fraction of that heritability that can be explained by known causative genetic variants (Manolio et al. 2009; Stranger et al. 2011). With the same criteria as in the single-trait analysis, the multitrait single-marker approach identified 12 markers (At1g11360-4, At1g31580-11, At2g14560-2, At2g17240-6, At2g26640-8, At2g45140-3, At3g10720-6, At3g56360-7, At5g06660-5, At5g… The fitness and wing data were approximately normally distributed (summary statistics Table 1) and were not standardized; however, the data were centered on their trait-specific means and interlandmark distance values were rescaled (all… Quantitative trait locus (QTL) mapping studies in S. cerevisiae have characterized the genetic architecture of complex traits, including global gene expression and resistance to small molecules [13], [14], [15], [16], as well as shed light… bioRxiv - the preprint server for biology, operated by Cold Spring Harbor Laboratory, a research and educational institution Canine hip dysplasia (CHD) is characterised by a malformation of the hip joint, leading to osteoarthritis and lameness.

This shuffling ensured that estimates of variance of each trait remained the same at the among-line, within-line, and residual levels, but covariances among traits were disrupted. McGuigan et al. (2014) used this approach to demonstrate… Applications of quantitative genetics and conservation genetics often require measures of pairwise relationships between individuals, which, in the absence of known pedigree structure, can be estimated only by use of molecular markers. Of the eight traits, three showed high predictability, two had intermediate predictability, and two had low predictability. However, a quantitative analysis of soft sweeps that also accounts for other factors like population substructure is needed before any conclusions can be drawn.
