AN EXPERIMENTAL EVALUATION OF GENETIC CORRELATION [PDF]
ABSTRACT Heritability and genetic correlations realized from both single-trait and antagonistic index selection were compared with paternal half-sib estimates. Primary attention was focused on the genetic correlation between six-week body weight and six-week tail length.

Genetic correlations in mutation processes [PDF]
We study the role of phylogenetic trees on correlations in mutation processes. Generally, correlations decay exponentially with the generation number. We find that two distinct regimes of behavior exist. For mutation rates smaller than a critical rate, the underlying tree morphology is almost irrelevant, while mutation rates higher than this critical ...

Genetic correlates of phenotypic heterogeneity in autism [PDF]
AbstractThe substantial phenotypic heterogeneity in autism limits our understanding of its genetic aetiology. To address this gap, we investigated genetic differences between autistic individuals (Nmax= 12,893) based on core (i.e., social communication difficulties, and restricted and repetitive behaviours) and associated features of autism, co ...

Genetic parameters for dystocia, milk yield and age at first calving in Brazilian Holstein cows
The present study aims to estimate genetic parameters for dystocia, milk yield and age at first calving of Holstein cows reared in intensive production systems located in the southeastern region of Brazil.

Genetic analysis of cortical thickness and fractional anisotropy of water diffusion in the brain [PDF]
Objectives: The thickness of the brain’s cortical gray matter (GM) and the fractional anisotropy (FA) of the cerebral white matter (WM) each follow an inverted U-shape trajectory with age. The two measures are positively correlated and may be modulated

Identifying progressive imaging genetic patterns via multi-task sparse canonical correlation analysis: a longitudinal study of the ADNI cohort [PDF]
Motivation Identifying the genetic basis of the brain structure, function and disorder by using the imaging quantitative traits (QTs) as endophenotypes is an important task in brain science.

Environmental stress alters genetic regulation of novelty seeking in vervet monkeys. [PDF]
Considerable attention has been paid to identifying genetic influences and gene-environment interactions that increase vulnerability to environmental stressors, with promising but inconsistent results.

A COMPARISON OF GENETIC AND PHENOTYPIC CORRELATIONS [PDF]
Genetic variances and correlations lie at the center of quantitative evolutionary theory. They are often difficult to estimate, however, due to the large samples of related individuals that are required. I investigated the relationship of genetic- and phenotypic-correlation magnitudes and patterns in 41 pairs of matrices drawn from the literature in ...
