Developmental and gene expression changes during intra-puparial development in Chrysomya albiceps (Diptera: Calliphoridae)

Van der Westhuizen, Lucinda (University of the Free State, 2021-11)

Criminal investigations are dependent on postmortem interval estimations (PMI) to solve crimes by determining when a homicide occurred. Time of death is estimated using several components, including pathology; however, a ...

The role of emotional intelligence and a functional polymorphism in the MAO-A gene on aggression in humans

Laubscher, Nadia (University of the Free State, 2012-05)

Article 1: Aggression is a complex trait, with both genetic and environmental factors important in its aetiology. It is a universal problem, for which better solutions are needed. This study will focus mainly on the influence ...

Aspects of the genetics of human aggressive behaviour

Odendaal, Zurika (University of the Free State, 2012-12)

DNA profiling from the crop content of sarcophagidae spp. larvae

Barnard, Adri Marlene (University of the Free State, 2017-01)

English: Morphological analysis of insect evidence plays a significant role in crime scene investigation. With the influence of DNA analysis in forensic cases, which now also plays a key role in forensic entomology, more ...

The association of specific polymorphisms in the serotonergic system with aggressive, impulsive and suicidal behaviour

Louw, Susan (University of the Free State, 2016-06)

English: Suicidal behaviour and the consequences thereof are a major global issue and need to be researched in order to promote a better understanding of this maladaptive behaviour. However, understanding the aetiology of ...

The environmental and genetic aetiology of the severity and presence of attention and hyperactivity related disorders in a population from South Africa

Mansfield, Jade (University of the Free State, 2015-07)

English: Attention-Deficit Hyperactivity Disorder is a neurodevelopmental disorder characterised by symptoms of inattention, hyperactivity, and impulsivity. This disorder has been increasingly diagnosed in children and ...

Aspects of the genetics of human aggressive behaviour

Cross-species microsatellite markers for the detection of hybrids in the genus connochaetes

Wessels, Letecia (University of the Free State, 2013-07)

Black wildebeest (Connochaetes gnou), a species endemic to South Africa, experienced two bottlenecks in the last century and the number of animals ultimately decreased to approximately 300. These bottlenecks led to a ...

Genetic variation in the most primitive Clivia species

Van der Westhuizen, Hester Maria (University of the Free State, 2010-11)

English: The genus Clivia Lindl., which belongs to the family Amaryllidaceae J. St-Hil. (1805), is comprised out of seven different species. Clivia nobilis, C. caulescens, C. miniata, C. gardenii, C. mirabilis, C. robusta ...

Identification and expression analysis of flavonoid biosynthetic genes in the genus Clivia

Snyman, Marius Christian (University of the Free State, 2010)

English: Anthocyanins belong to a large group of secondary plant metabolites, the flavonoids, and fulfil a range of biological functions that include the cyanic pigmentation they provide to flowers, fruits, vegetables and ...

A taxonomic review of the genus Microacontias (Scincidae: Acontiinae) based on DNA and morphological data

Janse van Vuuren, Lucas Cornelius (University of the Free State, 2009)

The recent taxonomic review of the legless, fossorial skink genus Acontias by Daniels et al. (2006), using DNA sequence data, led to the erecting of the new genus Microacontias for all the small-bodied taxa. These are ...

Genetic variation of Clivia caulescens

Stegmann, Suzanne (University of the Free State, 2011-06)

English: At present, the genus Clivia consists of six species, including Clivia nobilis Lindl., C. miniata (Lindl.) Regel, C. gardenii Hook., C. caulescens RA Dyer, C. mirabilis Rourke and C. robusta Murray, Ran, De Lange, ...

Bt expression in maize plant tissues and the impact of gene flow

Richardson, Grant Anthony (University of the Free State, 2012)

In 2007, the first case of field resistance to Cry1Ab was reported in South Africa, which is a concern as it negates the benefit of this technology. It has been suggested that a major contributing factor to the development ...

Genetic diversity in the Afrikaner cattle breed

Pienaar, Lené (University of the Free State, 2014)

English: This study was a first attempt to use microsatellite markers to determine the genetic diversity in an indigenous cattle breed, namely the Afrikaner. It was also the first study to combine genetic markers and ...

Screening of young and/or familial African breast cancer patients for the presence of BRCA mutations

Peter, Namhla (University of the Free State, 2014-01)

English: Screening for mutations within the BRCA1 and BRCA2 genes is a daunting task due to the length of the genes and the absence of mutational hotspots. An additional contributing factor is the genetic diversity within ...

Genetic connectivity, population dynamics and habitat selection of the southern ground hornbill (Bucorvus leadbeateri) in the Limpopo province

Theron, Nicholas Terence (University of the Free State, 2011-03)

Southern ground hornbills (Bucorvus leadbeateri) (SGH) are co-operative breeders that occur in groups of 2-9 individuals. Long life spans, large territory sizes (100km²), and low reproductive rates render these birds ...
