Investigating local ancestry inference models in mixed ancestry individual genomes
… Known admixed populations include the mixed ancestry of South Africa, Latin Americans and African Americans. Admixed individuals play important roles in understanding population history, disease aetiology, and personal genomics. Accordingly, efforts have been made to understand the genetic …

Ancestry determination using geometric morphometrics
Ancestry identification is an important aspect in forensic anthropological investigations concerning the biological and social identity of unidentified human remains. Traditionally, ancestry is usually assessed by the visual examination of the shape and form of the features of the skull and/or …

Ancestry Informative Markers Tailored to Hispanic Populations
… population; this makes an accurate panel of ancestry informative markers (AIMs) especially important for human identification. In Chapter 2, the Genomic Origins and Admixture in Latinos (GOAL) dataset containing 494,886 SNPs was used for SNP ascertainment. Utilizing a country attributable …

The Ancestry and Function of Cytochrome c6A
… This study aims to provide insight into the ancestry and function of cytochrome c6A. To gain a clearer understanding of the evolutionary history of cytochrome c6A and cyanobacterial homologues cytochrome c6B and c6C, phylogenetic analysis was performed on peptide sequences of these proteins …

A multi-ancestry genetic analysis of type 2 diabetes
… cohort of predominantly South Asian genetic ancestry, a particularly underrepresented population in T2D genetic studies. Using both imputed and sequenced genetic data from BELIEVE, I perform the largest genetic analysis of T2D in South Asian individuals to date, characterising the genetic …

The Distribution of Neanderthal Ancestry Across Populations And Within Genomes
… human populations carry some amount of archaic ancestry. The complexities of this admixture history, however, have persisted as outstanding questions in the field of archaic genomics. This dissertation focuses on some of these questions. In the first chapters of this dissertation, I focus on …

Sex and Ancestry Estimation Using the Base of the Cranium
Discriminant function analysis was employed to test sexual dimorphism and ancestral differences in the basicrania of European Americans and African Americans. The data used was originally collected on crania from the Terry and Bass III Donated Collections, using a three-dimensional digitizer. The …

Genetic ancestry and population health: elucidating the relative role of African genetic ancestry in cancer genomics and the broader implications for racial health disparities in cancer
… Among these groups, individuals of African ancestry, particularly African Americans, face some of the most severe outcomes, including higher incidence rates, delayed diagnoses, poorer prognoses, reduced survival, and less effective responses to treatment. While historical and systemic …

Ethnic admixture in African American ancestry as reflected in dental patterns
While the mixture of genes with those of European descent has been studied rather thoroughly, the African-Native-American-Asian-American admixture has not been as widely acknowledged or studied in the United States; Since shovel shaped incisors occur more frequently among Native Americans and …

The basis of racial classification: Ancestry-informative marker versus social context
… to examine the bases of racial classification: ancestry-informative marker (AIM) and social context. Two specific research questions guide this study. First, does AIM play a role in racial classification? Second, what is the role of social context in racial classification? This study proposes a …

Ancestry-based Methods for Characterizing the Evolutionary History of Admixed Populations
… together to form a new population with genetic ancestry from those sources. Admixture is ubiquitous across the tree of life, including humans, and is often associated with migration and exposure to new environments and selective pressures. Admixed populations provide a unique opportunity to …

Use of machine learning techniques for SNP based prediction of ancestry
Some have argued that the genetic differences between continentally defined groups are relatively small and unlikely to have biomedical significance. In this study, the extent of variation between continentally defined groups was evaluated. Small numbers of randomly selected single nucleotide …

Growth Analysis of Mixed Ancestry Infants Aged 0 – 18 months, South Africa
… in life. In South Africa, children of mixed ancestry (MA, 1-10 years) have a significantly higher risk for stunting (according to WHO growth standards) compared to other population groups. Adults of MA have the second highest type II diabetes mellitus prevalence, and hypertension doubled …

Population dynamics in first millennium BCE Italy: mobility and ancestry at Fermo, Marche
<p class="MsoNormal">Human migration is a crucial component in the formation of a community and a fundamental aspect of the socio-politic dynamic of a group. Exploring human migration in prehistoric contexts implies many challenges due to the absence of written documents or information other than …
