POPULATION GENETICS (FRUITFLY) NAME: Christopher N. Anah CLASS: BIOL 2108L INSTRUCTOR: DR. JAMES BATTEY OVERVIEW: In this lab the Drosophila melanogaster fly species were used to do genetic test crosses. Students were taught how to manipulate phenotypes‚ collect data from F1 through the F4 generations‚ and analyze the results.INTRODUCTION: The basic principles of genetics are very often shared by a vast array of organisms. For that reason‚ it is usually only necessary to study the genetic structure

Issues Associated with Genetic Modification of Plant for Crop Plantation Genetic modification of plant for crop plantation presents to create or maximise desirable characteristic of plant‚ such as increased yield‚ to produce better quality food and resistance to disease or resistance to climatic extremes like heat‚ cold and frost. However‚ most consumers have doubts about genetic modification plants on a less easily defined level. Many consumers could not accept genetic modified plant due to personal

1) Explain the moral issues involved in Genetic engineering. Genetic engineering is the modification of an organism by changing its genetic material. Genes can be transferred from different organisms and this makes many things possible with genetic engineering. Examples of genetic engineering include taking the insulin gene and using bacteria to create quick and cheap insulin to treat diabetics. Genetic engineering can also be used on food. For example‚ people lacking vitamin A in their diet can

Microevolution is the change in the genetic makeup of the gene pool of a population. It refers to the change in allelic frequencies that occur from generation to generation. There are three ways that microevolution can occur: mutation‚ genetic drift and natural selection. Mutation is the change in a gene of the DNA of an organism. This may change an allele and possibly the alleles frequency in the gene pool of the population. Genetic drift is an unpredictable change in a populations allelic frequencies

How are genetics being linked to cancer diagnosis? Your name COM/156 12/10/2011 Fung Yuen Chang How are genetics being linked to cancer diagnosis? Is it a possibility that cancer can be related to hereditary genetic factors? What are the possibilities of genetics playing a role in cancer diagnosis? Genetic research and its correlation to cancer is a topic on the forefront of many research labs today. Many cancers are being researched for their connection with just common genetic makeup

In Margaret Atwood’s novel Oryx and Crake‚ Atwood argues that genetic modifications are harmful to society instead of being helpful. Atwood shows this by describing all of the disasters that have taken place because of the genetically modified children. In the novel‚ genetic modifications start in animals‚ and then slowly progress to humans. When the modifications were taking place in animals there were a lot of people that knew about it‚ but once it switched over to the human population the people

Genetic Drift as an Evolutionary Force Becky Gonzalez Genetics 2450 Lab Section 1262 March 2‚ 2011 Genetic Drift as an Evolutionary Force Genetic drift‚ along with natural selection‚ mutation‚ and gene flow‚ is one of the basic evolutionary forces of evolution. Evolution is the method by which allele frequencies in a population change over time. This process can be random‚ where the changes occur through genetic drift (Hahn and Bentley 2003)

type of Opitz syndrome was linked to 22q deletion syndrome. The 22q11.2 deletion is now thought to be the original cause of the medical problems for some patients with Opitz G/BBB syndrome. Symptoms and Diagnosis: Opitz G/BBB syndrome is a genetic condition that affects several structures along the midline of the body. The most common features of this condition are: •wide-spaced eyes (hypertelorism) •defects of the larynx‚ and trachea‚ causing breathing problems and difficulty swallowing

Adopting a value-neutral position in genetic counseling is not always a good thing and sometimes may not be possible. There are many reasons why it is not always a good thing and why sometimes it may not be possible. One reason why adopting a value-neutral position is not always a good thing is because sometimes it can be seen as the genetic counseling is making a decision for the person whom has a problem. For example‚ if a woman has a disease and it is seen that it can affect the unborn fetus and

Although genetic testing can benefit society in numerous ways‚ such as the diagnosis of vulnerabilities to inherited diseases and ancestry verification‚ it also has the precarious capability to become a tool in selecting a more favorable genetic makeup of an individuals and ultimately cloning humans. Genetic testing will depreciate our quality of life and may result in discrimination‚ invasion of privacy‚ and harmful gene therapy. In 1993 a pamphlet by National Heart‚ Lung‚ and Blood Institute
