Probability and paternity: the utility of probability theory in the legal determination of facts in issue with particular reference to the resolution of paternity disputesPark, M. M. Unknown Date (has links) (PDF)
In this thesis it is proposed to examine the forensic application of probability to judicial or curial decision making, both in general and with particular reference to the determination of parentage such as is required in a paternity suit.

Inheritance of resistance to selected pyrethroid insecticides in <i>Blattella germanica</i> (Dictyoptera: Blattellidae)Ebbett, Raymond H. 09 May 2009 (has links)
Four insecticides, cypermethrin, fenvalerate, permethrin and phenothrin were employed to study the inheritance of resistance to pyrethroid insecticides in the Seasons strain of <i>Blattella germanica</i>. This resistance was found to be an autosomal, probably monofactorial character, not linked with the black body or orange body mutants that identify linkage groups 4 and 6.
The trait was found to be incompletely recessive with a degree of dominance of -0.57. It was established that the gene is probably separate and distinct from the known trait <i>R-pyreth</i>, a pyrethrins resistance gene linked with black body in the linkage map of this organism.
Future studies are recommended to further delineate this resistance and suggestions are made for possible avenues to pursue. / Master of Science

Modéliser l'évolution de la relation génotype-phénotypes dans des réseaux de régulation / Evolutionary modelling of genotype-phenotypes relation in regulatory networksOdorico, Andréas 12 December 2019 (has links)
L’identification de l’information génétique comme support de l’hérédité a accordé aux gènes une importance majeure dans l’étude de l’évolution et des mécanismes permettant la mise en place des caractères. Cependant, les processus permettant à une variation génétique de se traduire en variation phénotypique sont complexes et leur identification est centrale pour la compréhension de l’évolution.On parle de relation génotype-phénotype pour désigner la fonction qui relie l’espace des gènes à celui des caractères. Étudier les propriétés de cette relation permet d’identifier des mécanismes pouvant altérer les trajectoires évolutives et améliorer notre compréhension de l’évolution de systèmes vivants. Je défends notamment l’intérêt d’étudier mécanistiquement les processus par lesquels une variation génétique donne naissance à une variation phénotypique, et emploie, pour ce faire, un modèle de réseau de régulation transcriptionnelle.Ici, j’étudie les effets d’une information environnementale sur la relation génotype-phénotype et ses propriétés (notamment sa canalisation, sa robustesse à des perturbations génétiques ou environnementales). Pour ce faire, l’évolution de réseaux de régulation simulés est étudiée en présence d’un gène senseur de l’environnement ou d’une forme d’hérédité non génétique.Ce manuscrit débute par une discussion générale de l’intérêt des approches par modélisation, notamment pour l’étude de phénomènes complexes. Enfin, les résultats obtenus sont présentés en regard des discussions sur la nécessité d’une « synthèse évolutive étendue » pour décrire le processus évolutif d’une manière difficilement accessible par une approche gène-centrée. / The identification of genetic information as the as a physical basis for heredity put genes in the spotlight for the study of evolution and of the mechanisms shaping characters. However, the processes allowing genetic variation to translate into phenotypic variation are complex and their identification is crucial for the study of evolution.Genotype-phenotype relationship designates the function connecting the genotype and the phenotype spaces. Studying its properties will shed the light on mechanisms able to alter evolutionary trajectories and improve our understanding of the evolutionary process. I defend the importance of a mechanistic study of the processes translating genetic variation into a phenotypic one and use a model of transcriptional regulation networks to do so.This study tackles the topic of the effects of an environmental information on the genotype-phenotype relationship and its properties (especially canalization, the robustness of a phenotype to genetic or environmental disturbances). To do so, I studied the evolution of simulated regulatory networks in presence of a gene acting as an environmental sensor as well as in presence of non genetic inheritance.This document begins with a general discussion on the purpose of modelling approaches and the insights they bring on the study of complex phenomena. The results are discussed in the light of the debates on the necessity of an « evolutionary extended synthesis » to describe the evolutionary processes in a way hardly available with the gene-centered approach
