We present estimates of heritability for carcass traits of cattle published in the scientific literature. Seventy-two papers published from 1962 to 2004, which reported estimates of heritability for carcass traits, were reviewed. The unweighted means of estimates of heritability for 14 carcass traits by slaughter end point (age, weight, and fat depth) were calculated. Among the three end points...

"Missing heritability" in genome wide association studies, the failure to account for a considerable fraction of heritability by the variants detected, is a current puzzle in human genetics. For solving this puzzle the involvement of genetic variants like rare single nucleotide polymorphisms (SNPs) and copy number variations (CNVs) has been proposed. Many papers have published estimating the he...

The objective of the article is to investigate the variability in growth and wood properties of the willow clones. The growth and wood traits of four year old 21 clones willow clones were investigated. Analysis of variance showed that willow clones differed significantly for all the studied growth and wood traits. Among the growth parameters the maximum heritability value was shown by height wh...

Characters with phenotypic expression consisting of a response in one of several mutually exclusive and exhaustive categories are considered. Formulae relating heritability in the discrete, outward scale to heritability in underlying normal and exponential scales are presented. For the normal case with two response categories, results reduce to the well-known formula for heritability of binary ...

Abstract Background Heritability is a central measure in genetics quantifying how much of the variability observed trait attributable to genetic differences. Existing methods for estimating heritability are most often based on random-effect models, typically computational reasons. The alternative using fixed-effect model has received more limited attention literature. Results In this paper, we ...
