Quantitative genetics of disease traits [PDF]
SummaryJohn James authored two key papers on the theory of risk to relatives for binary disease traits and the relationship between parameters on the observed binary scale and an unobserved scale of liability (James Annals of Human Genetics, 1971; 35: 47; Reich, James and Morris Annals of Human Genetics, 1972; 36: 163). These two papers are John James’

Quantitative Genetics and Evolution
Today, evolution is a unifying concept in biology. A century and half ago, Darwin developed the theory of natural selection, and proposed it as the mainmechanism of evolution. A quantitative approach to the study of evolution required new theoretical developments in population and quantitative genetics. Here, I review the basic concepts of quantitative

COMPARISON OF QUANTITATIVE GENETIC PARAMETERS [PDF]
Shaw (1991) has described a maximum-likelihood procedure for comparing genetic covariance matrices between populations. While her efforts to expand the procedures available for quantitative genetic analyses are laudable, her discussion is incomplete in several respects. For example, consider her criticism of Dietz's matrix permutation test (Dietz, 1983)

Genomic prediction using a reference population of multiple pure breeds and admixed individuals
Background In dairy cattle populations in which crossbreeding has been used, animals show some level of diversity in their origins. In rotational crossbreeding, for instance, crossbred dams are mated with purebred sires from different pure breeds, and ...

Background Survival from birth to slaughter is an important economic trait in commercial pig productions. Increasing survival can improve both economic efficiency and animal welfare. The aim of this study is to explore the impact of genotyping strategies

QUANTITATIVE GENETICS OF HETEROCHRONY [PDF]
A model of quantitative-genetic variation in developmental processes is introduced and analyzed. The model is of a bifurcating sequence of events in which traits develop from the same tissue until a transition occurs, after which they develop partially independently.

Accuracy of multi-trait genomic selection using different methods [PDF]
Background Genomic selection has become a very important tool in animal genetics and is rapidly emerging in plant genetics. It holds the promise to be particularly beneficial to select for traits that are difficult or expensive to measure, such as traits

Background Barley is the world’s fourth most cultivated cereal and is an important crop model for genetic studies. One layer of genomic information that remains poorly explored in barley is presence/absence variation (PAV), which has been suggested to ...

Selection for the number of living pigs on day 11 (L11) aims to reduce piglet mortality and increase litter size simultaneously. This approach could be sub-optimal, especially for organic pig breeding.

Genomic prediction in Nordic Red dairy cattle considering breed origin of alleles
: This study investigated the reliability of genomic prediction (GP) using breed origin of alleles (BOA) approach in the Nordic Red (RDC) population, which has an admixed population structure.
