We show in an idealized model that the narrow sense (linear) heritability from d autosomal SNPs can be estimated without bias from n independently sampled individuals, by a method of moments strategy based on quasi-regression. The variance of this estimator is below C1/n+C2d /n for constants Cj <∞, uniformly in n > 2 and d > 1. In particular d n is allowed, and heritability can be consistently ...

OBJECTIVE The current study aimed to describe what proportion of variation in adult alcohol intake is attributable to genetic differences among individuals and what proportion to differences in environmental experiences individuals have been exposed to. Effects of age, gender, spousal resemblance, and cultural transmission of alcohol intake from parents to offspring were taken into account. M...

INTRODUCTION Circulating levels of the inflammatory marker YKL-40 are elevated in cardiovascular disease and obesity-related type 2 diabetes (T2D), and serum YKL-40 levels are related to elements of dyslipidaemia. OBJECTIVE We aimed to investigate the associations between serum YKL-40 and obesity-related traits in a Danish sample of non-diabetic relatives to T2D patients and, furthermore, to ...

A diallel cross from seven parents and their F1 hybrids were evaluated across three locations using a Randomized complete block design with replications for quantitative traits performance. Parameters assessed include plant heights, days to 50% headings, panicle lengths, weights, number of seeds per panicle, productive tillers, branches, yield plots which extrapolated in tonnes hectare 100 grai...

Marker-based methods for estimating heritability and genetic correlation in the wild have attracted interest because traditional methods may be impractical or introduce bias via G x E effects, mating system variation, and sampling effects. However, they have not been widely used, especially in plants. A regression-based approach, which uses a continuous measure of genetic relatedness, promises ...

a partial set of diallel crosses conducted among seven bread wheat genotypes contain (gasspard,m86-4,m86-6,dn-11,ws82-9 and m86-12) along with 21 hybrid, based on randomized complete block design(rcbd) with three replication were evaluated. the experiment was accomplished in a research field of agriculture and natural research center of tehran province in 2012-2013 in order to study genetic ana...

Fifty genotypes of CIMMYT bread wheat were evaluated at Agricultural Research Farm, BHU, Varanasi during 2019-2020.The analysis variance revealed significant differences among for all traits. High Phenotypic coefficient variation was recorded compared to the genotypic variation. However, high coefficients found particularly for: grain yield per plot (8.71), harvest index (9.22), test weight (8....
