Genetics With Drosophila Flies Josh Derrall Lab Group: Dana Gilkes James Lupo Olivia Giannola December 4‚ 2012 Prof. Hunter Introduction Genetics is a topic that has been studied for hundreds of years. One of the most notable geneticists was Gregor Mendel. Mendel studied basic inheritance patterns and gene expression using pea plants. Mendel determined that the offspring of two parents contains one gene from each parent (McKusick 1983). However‚ since Mendels discoveries

response to a socio-scientific issue. The use of IVF and preimplantation genetic diagnosis (PGD) Preimplantation genetic diagnosis (PGD) is the process of identifying genetic defects within an embryo before implantation‚ PGD allows the embryos DNA to be studied for mutations and genetic diseases. Originally PGD was used on female embryos and was used to prevent pregnancy termination in pregnancies with high risks of a sex linked genetic disease. Process The IVF procedure consists of ovarian stimulation

Discuss genetic explanations for aggression. Early research concentrated on chromosomal abnormalities but no specific genotype has been associated with aggression. Genes determine how much testosterone a person’s body produces and how quickly it circulates around their body. Genes also determine the synthesis of testosterone receptors‚ and how many and how sensitive such receptors are. The gene called monoamine oxidase A (MAOA) produces an enzyme which regulates the metabolism of serotonin in

Ethical Considerations As a Dietetic Practitioner Ethical considerations are vital to businesses to help create an understanding of boundaries and aid in decision making. As a dietetics practitioner communicates with coworkers and clients‚ one is essentially representing the company. To understand the importance of ethics‚ one must first understand situations when a code of ethics is needed. In such a diverse country‚ it is important to provide service that is sensitive and considerate of cultural

DROSOPHILA GENETICS DROSOPHILA CULTURE We will study basic principles of Mendelian inheritance with the use of the fruit fly‚ Drosophila melanogaster [the name means “black-bodied fruit-lover”]. Drosophila was one of the first organisms to be studied genetically: its small size‚ short life cycle (10 ~14 days at 25oC)‚ high reproductive rate (an adult female can lay 400-500 eggs in 10 days)‚ and ease of culture and genetic manipulation have made it perhaps the best understood animal genetic system.

Genetic models to explain heterosis Traditional genetic analyses of heterosis are based on the quantitative effects of the genes between two opposite inbred lines. Three major classical genetic models have been suggested to explain the hybrid vigor: the dominance hypothesis explains increased vigor to the action at multiple loci of favorable dominant

Genetic Diversity In Agriculture Genetic variation is the raw material for the plant breeder‚ who must often select from primitive and wild plants‚ including wild species‚ in search of new genes. The appearance of new diseases‚ new pests‚ or new virulent forms of disease causing organisms makes it imperative that the plant be preserved‚ because it offers a potential for the presence of disease resistant genes not present in cultivated varieties. Also‚ there are demands for new characters-- for
