Surname Distributions, Origins, and their Association with Y-chromosome Markers in the Aleutian Archipelago
… as well as their association with Y-chromosome haplogroups found in Native communities from the Aleutian Archipelago. The project's underlying hypothesis is that surnames and Y-chromosome haplogroups are correlated in the Aleutian Islands because both are paternally inherited markers. Using 732 …

DNA Sequence and Haplotype Variation Analyses of Circadian Clock Genes and Their Effects on Phenotypes in the Turkey, Meleagris gallopavo
… identified from the genes that screened. The haplogroups in the turClock gene were significantly associated with body weight (BW) at 309 d of age, feed conversion ratio (FCR) for 34 - 68 d and 69 - 159 d, egg production and average egg weight (P " 0.05). The haplogroups developed from …

Pharmacogenomics and pharmacokinetics of antiretroviral drugs and their associations with metabolic complications in HIV-infected Black South Africans
… associations of mitochondrial DNA (mtDNA) haplogroups and ART related metabolic complications, characterized relationships between genetic polymorphisms and plasma efavirenz concentrations, and investigated associations between plasma efavirenz/lopinavir concentrations and lipid and glucose …

Using ancient DNA to infer impacts of European colonization on first nations populations in coastal British Columbia, Canada
… and the majority of present-day Y-chromosome haplogroups belong to those commonly found today in European populations. Since the mtDNA of present-day individuals exhibited a very low frequency of haplogroups commonly found in Europe, this indicates a sex-biased effect of colonization where the …

Identifying and Tracking the Evolution of Mutations in the SARS-CoV-2 Virus
… on the spike protein by focusing on the haplogroups of the sequences across the world. A comprehensive database linking three important, currently available databases is curated as part of this study to fill the gaps caused by sequencing errors. Further, this study exploits the data …

Functional Genome-wide Association Studies (fGWAS) and genomics landscape of signatures of polygenic adaptation in Botswana populations with HIV-1 C infection
… Analyses of phylogenetic relatedness and haplogroups were also conducted. The mtDNA sequences' median coverage was (1060; Q1:738.5 – Q3:1397). The total genotyping rate for mtDNA QC was 0.99, with 560 variations being eliminated because of minor allele criteria of 0.01. We then discovered …

Mitochondrial Haplotype Influences the Impact of Simulated Climate Warming on a Tropical Ectotherm
… two sympatric but highly divergent mitochondrial haplogroups in this pseudoscorpion to evaluate the potential impact of mitochondrial sequence variation on fitness traits and response to climate change. For survivorship and sperm production, my results reveal a significant interaction between …

BRUCELLOSIS TRANSMISSION BETWEEN WILDLIFE AND LIVESTOCK IN THE GREATER YELLOWSTONE ECOSYSTEM: INFERENCES FROM DNA GENOTYPING
… A haplotype network consisting of 54 individual haplogroups was generated from these isolates using Network v4.61. Network assessments of genetic relatedness among Brucella isolates showed that genotypes from the 2008 cattle outbreak in Wyoming matched elk B. abortus genotypes, confirming elk as …

The Use Of Pyrosequencing For The Analysis Of Y Chromosome Single Nucleotide Polymorphisms
… three different racial groups into 15 different haplogroups. The Y chromosome SNP analysis system developed utilized nested PCR for the amplification of all 13 loci. Then they were sequenced as groups, ranging from one to three loci, in a single reaction. The Y chromosome SNP analysis system …

Sisters' curse: sexually antagonistic selection constrains the spread of a rare mitochondrial haplogroup
… of two highly divergent mitochondrial haplogroups, Clades A and B2, in central Panamá. DNA profiling demonstrated that B2-haplogroup males enjoyed a significant sperm competitive advantage, siring 2.5 times as many offspring as A- haplogroup males in two-male sperm competition …

Systematics, Biogeography, and Phylogeography of Thylamys Mouse Opossums, a Recent Radiation of Neotropical Marsupials
… numerous morphologically cryptic mitochondrial haplogroups within four species. In Chapter 2, I assess the evolutionary independence of a subset of these morphologically cryptic lineages within the montane species <italic>Thylamys pallidior</italic>, <italic>T. sponsorius</italic>, and …

Mitochondrial genetic variation in the evolution of humans and metabolism of cancer
… of today. This study also identified new mtDNA haplogroups, many of which are among the earliest diverging lineages. This study contributes to the global mitochondrial haplogroup diversity knowledge bank. The role of mitochondrial genetic mutations was studied in the context of altered …

Human mitochondrial DNA and population structure of the Western Mediterranean Islands
… Mediterranean. The near disappearance of rare haplogroups such as U8 highlights the progressive loss of ancient maternal diversity through drift or later demographic replacements. Corsica, represented by modern data only, shows strong maternal proximity to Sardinia and western Sicily, …

Genetic variation among Zulu sheep sub-populations of South Africa assessed by microsatellites and mitochondrial DNA (mtDNA)
… respectively. Phylogenetic analysis showed two haplogroups (A and B). Haplogroup B lineage predominates among Zulu sheep with a frequency of 93%, while A lineage had a frequency of 7%. The analysis of mtDNA showed a high level of genetic diversity among Zulu sheep. The molecular information …

Genetic and biochemical analysis of materials from a medieval population from Ynys Mon North Wales
… degraded, an attempt was made at determining the haplogroups from the sequenced HV1 haplotypes based on likelihood. Generally, the site showed a high predominance of Haplotype K (5) followed by H (2) and U (2) haplogroup profiles.

Essays in development and urban economics
… based on the notion of paternal Y-chromosome DNA haplogroups. The resulting genetic diversity measure, which is rooted in long-term history, is less subject to the problem of endogeneity. In addition, the distances among different populations are accounted for in such fractionalization index. …
