Quantitative trait genetics today leverages Wright's observations about the statistical relationship between genotype and phenotype in families and populations to understand how certain genetic features can affect variation in natural and…

Quantitative genetics is built on dissecting the interplay of these factors by overlaying data on family trees and analyzing the correlation of various classes of relatives (1–3). In addition, family trees can serve as a multiplier for… - 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.

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…

Canine hip dysplasia (CHD) is characterised by a malformation of the hip joint, leading to osteoarthritis and lameness. Current breeding schemes against CHD have resulted in measurable but moderate responses.

Quantitative trait loci (QTL) for fatness traits were re- ported recently in For the mapping of QTLs representing major genes for meat qual- ity traits in livestock,  This and subsequent articles on the W (Kit) locus revealed the presence of modifiers of different strengths and, in the case of piebald, that some of these modifiers on their own could cause pigmentation abnormalities. The genotype of marker B is generated using information from markers A and E. The genotype of marker C is generated from the imputed genotype of marker B and the genotype of marker E.
