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

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

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

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)

Ethical Dilemmas in Genetic Patenting – A Utilitarian Perspective On August 16th‚ the U.S. Federal Circuit Court of Appeals upheld that Myriad Genetics in Salt Lake City‚ Utah‚ had the right to patent ‘isolated’ genes that are linked to ovarian and breast cancers.1 This means that Myriad Genetics can prevent others from using the BRCA1 and BRCA2 genes in research. It also means that Myriad can charge high prices from companies that wish to use these genes. This has raised arguments about the ethical

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

increased resistance to herbicides or improved nutritional content. The enhancement of desired traits has traditionally been undertaken through breeding‚ but conventional plant breeding methods can be very time consuming and are often not very precise. Genetic engineering‚ on the other hand‚ can create plants with the exact desired trait very rapidly and with great accuracy. For example‚ plant geneticists can isolate a gene responsible for drought tolerance and insert that gene into a different plant. The

essay I am going to discuss the case of a British couple that will have Britain’s first designer baby. I will cover the ethical issues regarding the topic of genetic engineering and also theories of Kantian Ethics and Utilitarianism to justify if genetic engineering is morally right. A British couple has bypassed strict laws in Britain for genetic screening by travelling to America and undergoing treatment which costs £30‚000 in order to conceive their desired child‚ in the hope to save their
