Heritability of Spontaneous Otoacoustic Emissions
Spontaneous otoacoustic emissions (SOEs) are narrow-band signals emitted from the cochlea and measured in the ear canal with a sensitive microphone. Because these emissions are correlated with sex and because sex is genetically determined, Bilger et al. (1990) hypothesized that SOEs were inherited. …

Epigenetic Heritability in Somatic Cells
… this thesis I present my findings on epigenetic heritability in somatic cells. The thesis consists of four main chapters. In the first chapter, I describe Memento, a maximum likelihood method I developed for inferring ancestral methylation states. The method takes a phylogeny of somatic cells and …

Assessing Multivariate Heritability through Nonparametric Methods
… of living subjects are often quantified by heritability. By distinguishing genotypic variation, or variation due to parental pairings, from phenotypic variation, or normal intraspecies variation, the heritability of traits can be estimated. Due to the multivariate nature of many traits, such …

Predictors of Hallux Valgus: a study of heritability
Hallux valgus is a complex progressive foot deformity of uncertan aetiology. The disorder is characterised by a lateral deviation of the hallux at the first metatarsophalangeal joint; an angle 150 is considered as clinical hallux valgus. A niodel that predicts first metatarsophalangeal joint angle …

Heritability estimates for calving date in Simmental cattle
… and had 19.6 ± 2.4 d longer calving intervals. Heritability estimates were .17 ± .04 for first calving date, .07 ± .06 for second calving date, .04:105 for calving interval and .11 ± .04 for percent return. Calving interval does not appear to be a useful selection criterion to improve …

Heritability of Nociception and Antinociception in the Laboratory Mouse
"Nociceptive and antinociceptive variability has been demonstrated in the mouse; a proportion of this variability is due to inherited genetic factors. We present genetic correlation analyses of 22 nociceptive measures among a common set of inbred mouse strains, revealing the existence of five …

A Proposed Framework for Establishing Optimal Genetic Designs for Estimating Narrow-sense Heritability
… so that one is able to estimate narrow-sense heritability with smallest possible variance, for a given amount of effort. We call this an optimal genetic design. The framework allows one to compare the variances of estimators of narrow-sense heritability, when estimated from each one of the …

Heritability and repeatability of speed for two- and three-year- old standardbred racehorses
… were adjusted for pace, repeatability and heritability estimates ranged from .32 ± .08 to .55 ± .04 and from -.25 ± .22 to .66 ± .15, respectively. Pooled estimates of t and h² were .44 ± .01 and .29 ± .03, respectively. When records were not adjusted for pace, sire, horse and error …

Investigating the heritability of resistance fueling copy number variation in glyphosate resistant Amaranthus palmeri
… circular DNA, which raises questions about the heritability of resistance gene copies. I used 799 F1 progeny from 30 crosses to examine the following: (i) Is there a relationship between EPSPS copy number (CN) of offspring and mean of the parental pair copy number? (ii) Is there variability in …

The heritability of history: how inherited status affects cooperative behaviour in public goods games
The intergenerational transmission of inequality causes individuals to receive unearned advantages and disadvantages in society. Understanding how the transmission of unearned material status affects social interactions will help to illuminate how the relationship between material status and social …

Heritability and repeatability estimates of first service conception and first cycle calving in Angus cattle
… In addition, given the nature of the phenotypes, heritability estimates of fertility traits are generally low, suggesting minimal genetic influence and therefore slow rates of genetic gain. First service conception (FSC) is a binary trait that describes the outcome of the first service of …

Disease population genetic simulation framework: towards application in modelling disease risk prediction and heritability rate

The Heritability of Seedling Stage Drought Resistance in Rape and Its Relationship to Seedling Root Morphology
This study examines the heritability of seedling-stage drought resistance in rape (Brassica campestris L.) and its association with seedling root morphology. The heritabilities of seedling stage drought resistance, based on percentage survival data from 40 half-sib families grown under high and low …
