The New Borderland: A Mixed-Methods Examination of Teacher Perceptions of Intelligence, Race, and Socioeconomic Status in Relation to Behavior Genetics
Behavior genetics argues intelligence and educational attainment are highly heritable (genetically influenced) and polygenic (influenced by many genes) traits. Researchers in this field have moved beyond identifying whether and how much genes influence the manifestation of a given outcome to trying …

Genetics, behavior, and disease resistance in chickens
… designed to examine the interfacing of behavior, genetics, physiology and disease resistance in the domestic fowl. The principle objective was to obtain insights into the mechanisms involved in the responses of the domestic chicken to various husbandry situations. A second objective was …

Longitudinal relations between parenting and child big five personality traits
… some perspectives derived from research in behavior genetics minimize the role of parenting practices on children’s personality development. In order to shed some empirical light on these issues, I examined the long-term relations between parenting and child Big Five personality traits …

The contribution of nonshared environmental factors to differential parental discipline: A twin study
… is linked to children's later social skills and behavioral and emotional functioning. Prior studies have shown that parents treat their children differently. The purpose of this dissertation was to examine whether parents use differing levels of discipline with their children and to delineate …

A factor analytic-genetic approach to the relationship between morphology and behavior in mice
… factors, four of which were correlated with both behavioral and morphological measures. Analyses of variance on the individual factor scores indicated that genetic influences contributed to five of the factors and sex contributed to three of the factors. However none of the main effects of diet, …

Disuguaglianze sociali nella salute, tra eterogeneità individuale e fattori sociali di rischio
… from sociology, epidemiology, economics and behavioral genetics. In particular, I focus on two issues: the socio-economic determinants of health and BMI and the socio-economic gradient in health and BMI, trying to integrate the standard sociological approach with findings from behavior …

Tracing causes and consequences of human intelligence through genetic and cognitive data
… “genetic nurture”, through which the unique genetics of parents can give rise to passive gene-environment correlation that affects their offspring’s years of education. Study 2 explores the observation that faster reaction time (RT) on elementary cognitive tasks (ECTs) is associated with …

A longitudinal behavior genetic model for ordered categorical variables
A model for the analysis of longitudinal twin data consisting of ordered categorical variables was proposed. Proportional changes in response categories across time were modeled within growth curve by means of mean and variance changes in underlying continuous variables. Variances of the growth …

Heredity and the Human Condition: A Study of 20th Century Genetic Accounts of Alcoholism
This dissertation takes as its starting point some curious historical parallels in research on the heritability of alcoholism from opposite ends of the 20th century, and the underlying continuity in assumptions implicated by these parallels. Rather than review mainstream historical narratives on …

Genome-wide polygenic scores, executive function, and attention-deficit/hyperactivity disorder in youth
Although attention-deficit/hyperactivity disorder (ADHD) is highly heritable, the processes by which genetic risk affects its development are poorly understood. Potential mechanisms that may contribute to the development of ADHD, possibly by sharing common genetic risk, include impairments in …

Genomic response to selection for behavior
… is a model of significant interest to social behavior genomics because of an experimental breeding project that began in the mid-20th century at the Institute for Cytology and Genetics in Novosibirsk, Russia. In this experiment, foxes acquired from fox farms were bred into two lines: one that …

Fishing For The Evolutionary Bases Of Female Ornamentation
… been elusive. In my dissertation I examine the behavioral, hormonal, and genetic correlates of female throat coloration—a male typical trait—in the threespine stickleback fish (Gasterosteus aculeatus), to test whether the evolution of the female trait might be attributed to adaptive or …

Elucidation of the Role of miR-184 in the Development and Maintenance of the Drosophila Melanogaster Nervous System
MicroRNAs (miRNAs) are short, non-coding RNA sequences that are generated from longer primary transcripts (pri-miRNA). These pri-miRNAs are processed by the endonuclease Drosha into a hairpin secondary structure (pre-miRNA), exported from the nucleus and cleaved by the enzyme Dicer to form a duplex …

The Molecular Evolution of the Serotonin System in Macaques (MACACA): a Detailed Survey of Four Serotonin-Related Genes
… been implicated in the regulation of critical behaviors, such as those related to aggression or impulse control. However, most research on serotonin has focused on the proximate connection to behavior, and little is known about its evolution. This is unfortunate, since the serotonin system has …
