Problem: It is often assumed that the heritability of performance traits (function) can be estimated by the heritability of primary traits (e.g. form). It is also frequently assumed that performance traits should be less heritable than primary traits. These assumptions should be carefully evaluated rather than assumed. One common area of study in which these assumptions have been made is anti-p...
in order to assess the heritability of short vegetation period (early maturity) of sugar beet hybrids, an experiment was carried out in randomized complete block (rcb) design with 4 replications in abdolrasoul motahari agricaltural research station of sugar beet seed institute, karaj, iran in 2009. in this research, the heredity of the traits in testcrosses derived from crosses of 18 half sib f...
Genetic variability, heritability in broad sense and expected genetic advance as percent of mean for fruit yield and nine characters were studied in 25 pointed gourd genotypes. Fruits per plant and fruit yield per plant showed maximum variability. Genotypic coefficient of variation was found high for fruit yield and number of fruits per plant. All the characters under study were highly heritabl...
Genome-wide significant associations generally explain only a small proportion of the narrow-sense heritability of complex disease (h). While considerably more heritability is explained by all genotyped SNPs (hg ), for most traits, much heritability remains missing (hg 2 < h). Rare variants, poorly tagged by genotyped SNPs, are a major potential source of the gap between hg 2 and h. Recent effo...
Efforts to identify loci underlying complex traits generally assume that most genetic variance is additive. Here, we examined the genetics of Arabidopsis thaliana root length and found that the genomic narrow-sense heritability for this trait in the examined population was statistically zero. The low amount of additive genetic variance that could be captured by the genome-wide genotypes likely ...
abstract in order to study the inheritance of grain yield and its components in bread wheat, two cultivars, karchyya(drought and salinity tolerant) and gaspard (sensitive to drought and salinity stress) were crossed.parents together with f1, f2, f3, bc1and bc2 generations were evaluated using a randomized complete block design with three replications in 2008-2009 growing season.grain weight per...
A plethora of genetic association analyses have identified several genetic risk loci. Technological and statistical advancements have now led to the identification of not only common genetic variants, but also low-frequency variants, structural variants, and environmental factors, as well as multi-omics variations that affect the phenotypic variance of complex traits in a population, thus refer...
The response to intradermally injected phytohaemagglutinin (PHA-response) is a commonly used quantification of avian immunocompetence (the ability to resist pathogens). Parasite-mediated sexual selection requires heritable immunocompetence, but evidence for heritability of PHA-response in birds largely stems from full-sib comparisons. Using an animal model approach, we quantified the narrow-sen...
The narrow-sense heritability and expected selection response are very important to be recognized in the F2 population of maize determine character selected. This study aimed estimate narrow-senseheritability quantitative characters population. experimental method used this was field experiments on dry land using pumping wells for irrigation. conducted from April October 2022 Amor-Amor Hamlet, ...
Genetic components controlling a number of nutrient quality traits in rice (Oryza sativa L.) were studied using 7×7 half a diallel cross. This experiment were carried out for determination of gene action, estimation of heritability and determination the best parents. The contents of P, K, Fe, Zn and Mn were measured from white rice grain flour obtained from studied genotypes. Analysis of varian...
