Characterisation of eight non-codis Ministrs in four South African populations to aid the analysis of degraded DNA
Ismail, Aneesah (University of the Western Cape, 2009)In many forensic cases, such as mass disasters reconstruction cases, the recovered DNA is highly degraded. In such incidences, typing of STR loci has become one of the most powerful tools for retrieving information from ... -
Development of a COMT PCR multiplex to investigate resilience, anxiety and childhood trauma in a South African population
Jacobs, Sarah (University of the Western Cape, 2020)Anxiety, resilience and childhood trauma can be categorized as functional behavioural categories, with a wealth of research behind each. The research approach adopted for each, in most cases, is either from a genetic or ... -
Differences in visual attention processing: An event-related potential comparative analysis within psychotic disorders
Williams, Kimberley Clare (University of the Western Cape, 2018)Introduction: Sustained attention is known to be dysfunctional in psychotic disorders. Sustained attention is the ability to remain focused on a specific time-locked stimulus within a task. We aimed to determine whether ... -
Differences in visual attention processing: An event-related potential comparative analysis within psychotic disorders
Williams, Kimberley Clare (University of the Western Cape, 2019)INTRODUCTION: Sustained attention is known to be dysfunctional in psychotic disorders. Sustained attention is the ability to remain focused on a specific time-locked stimulus within a task. We aimed to determine whether ... -
A dual analysis of the South African Griqua population using ancestry informative mitochondrial DNA and discriminatory short tandem repeats on the Y chromosome
Heynes, Kirstie (University of the Western Cape, 2015)The primary objective of this Masters project was to investigate the maternal ancient substructure of the Griqua population in South Africa. Genetic ancestry was determined by investigating ancestry informative single ... -
Evaluation of insertion-deletion polymorphisms with the kit Qiagen Investigator® DIPplex for forensic application in South Africa
Jacobs, Gwynneth (University of the Western Cape, 2015)Insertion-deletion polymorphisms (indels) have been underutilized in forensic identification of individuals in comparison with single nucleotide polymorphisms (SNPs) and short tandem repeat (STRs) systems. The use of ... -
The evaluation of Y-STR loci for use in forensics
Ehrenreich, Liezle Suzette (University of the Western Cape, 2005)The aim of this study was to investigate the forensic usefulness of various Y-chromosome short tandem repeat loci among South African sub-populations. Three different sets of Y-chromosome short tandem repeat loci were ... -
A forensic analysis of genetic variation in the Botswana population
Tau, Tiroyamodimo (University of the Western cape, 2016)This thesis has been placed under a long term embargo. Forensic and population genetic parameters were investigated in the Botswana population using autosomal and Y-chromosome short tandem repeat markers. AmpFlSTR Profiler ... -
Forensic identification of six of Tanzanian populations using the extended haplotype markers
Mwema, Hadija Saidi (University of the Western Cape, 2011)The aim of the present study was to evaluate the power of discrimination and genetic (diversity) parameters in the Y chromosome extended haploytpe markers in populations of Tanzania for forensic and populations studies. ... -
The Internal Validation and Casework Application of MiniSTR Systems
Kleyn, Eugene Lyle (University of the Western Cape, 2008)The objective of the study was to conduct an internal validation on miniSTR systems and apply it to cases received from the South African Missing Persons Task Team (SAMPTT). This was prompted by the fact that miniSTR systems ... -
Molecular detection and characterisation of RNA viruses of honeybees
Topley, Elize Lindsay (University of the Western Cape, 2009)Propagation methods for honeybee viruses have not changed since these viruses were discovered. There are no suitable cell lines or cell culture techniques available for honeybee viruses. Honeybee viruses have to be manually ... -
Molecular detection and characterisation of RNA viruses of honeybees
Topley, Elize Lindsay (University of the Western Cape, 2009)Honeybees have evolved through the centuries to inhabit most parts of the world except for the extreme Polar Regions. These insects have also been susceptible to pathogens and disease which has always been part of the ... -
Molecular detection and genetic manipulation of the Black Queen Cell Virus
Benjeddou, Mongi (University of the Western Cape, 2002)The South African isolate of the Black Queen-Cell Virus (BQCV), a honeybee virus, was previously found to have an 8550 nucleotide genome excluding the poly(A) tail. Its genome contained two ORFs, a 5'-proximal ORF encoding ... -
Population structure and demographics in Nigerian populations utilizing Y-chromosome markers
Cole-Showers, Curtis Lanre (University of the Western Cape, 2014)Nigeria is peopled by ethnically and linguistically diverse populations of which little were known until the last few millennial. The absence of major natural geographical barrier increases the possibility of the populations ... -
Y-STR profiling of four South African populations using the University of the Western Cape 10 locus set
Tsiana, Kebareng Jacobeth (University of the Western Cape, 2015)In this study the 10 Y-specific loci of the University of the Western Cape (DYS710, DYS518 385a/b, DYS644, DYS612, DYS626, DYS504, DYS447, DYS447, and DYS481) were analysed in 492 individuals from South African population ...
