Are Genetic Correlations and Environmental Correlations Correlated? [PDF]
Nature, 1970 CORRELATIONS between different characters measured on individuals of a population have both genetic and environmental causes. In an extensive genetic analysis of the open-field behaviour of mice, which is a widely used index of “emotionality”, we have found that genetic and corresponding environmental patterns of association among pairs of characters ...

Genetic correlation in otosclerosis
American Journal of Otolaryngology, 1999The aim of this study was to determine the relationship of HLA typing in patients with otosclerosis.We used a prospective study in which HLA typing of 100 surgically confirmed otosclerosis patients were compared with age and sex matched normal individuals.HLA-A3, HLA-A9, HLA-A11, and HLA-B13 were found to be significantly higher (P < .05, .01, and .01,

The Genetic Correlation Between Procrastination and Impulsivity [PDF]
Twin Research and Human Genetics, 2014 The reported genetic correlation of 1.0 between the traits of procrastination and impulsivity (Gustavson, D. E., Miyake, A., Hewitt, J. K., & Friedman, N. P. (2014). Psychological Science), which was held to support an evolutionary origin of the relationship between the two traits, was tested in data from two large samples of twins from Australia ...

Genetic correlates of insight in schizophrenia
Schizophrenia Research, 2018Insight in schizophrenia is clinically important as it is associated with several adverse outcomes. Genetic contributions to insight are unknown. We examined genetic contributions to insight by investigating if polygenic risk scores (PRS) and candidate regions were associated with insight.Schizophrenia case-only analysis of the Clinical Antipsychotics ...

Genetic correlations in validating emotionality
Behavior Genetics, 1990Sixty-six rats of seven inbred strains were observed in an open field (OF) and in a light-dark preference box (LDB). Each set of apparatus provides measures of locomotor activity and of the time spent in the "most protected" area (the corners in the OF, the dark compartment in the LDB). These measures are proposed to be indices of emotionality.

Genetic correlates of efavirenz hypersusceptibility
AIDS, 2004Non-nucleoside reverse transcriptase inhibitor (NNRTI) hypersusceptibility is seen in approximately 30% of HIV isolates with nucleoside reverse transcriptase inhibitor (NRTI) resistance. NNRTI hypersusceptibility has been associated with improved outcomes to NNRTI-based therapy.To determine the genetic correlates of efavirenz hypersusceptibility.Paired

Estimating genetic correlations
Annals of Human Genetics, 1980A method is proposed for simultaneous estimation of genetical variance and covariance components for quantitative characters and hence correlations and cross-correlations between relatives. It proceeds by successive approximations, which are not difficult to compute. Judging by examples, they appear to converge rapidly in practice.

Inference about genetic correlations [PDF]
Behavior Genetics, 1988 In polygenic systems genetic correlations and the factors and specific genetic variances from genetic correlation matrices are often interpreted in terms of sets of genes common or specific to variables. While these inferences may indeed be true, a genetic correlation is not always sufficient evidence for the inferences.

Phenotypic, Genetic and Environmental Correlations [PDF]
Biometrics, 1961 and in many instances the estimate of a phenotypic correlation is reported smaller in magnitude than that of the corresponding genetic correlation, e.g. with certain poultry records, in Lerner & Cruden [1948], sheep records in Morley [1951] and with certain dairy records in VanVleck [1960] and Searle [1961]. Such results may seem a little unexpected at
