Genetics Research Project<br />Rory O’Riordan Period 8<br />
Basic Principles of Genetics<br /> 1. How are traits controlled by dominant and recessive alleles?<br />Dominant: One who’s trait always shows up in the organism when the allele is present.<br />Recessive: Masked or covered up when dominant allele is present.<br />2. How are traits controlled with co-dominant alleles?<br />Neither allele is masked in the offspring.<br /> 3. Explain how the alleles of two parents combine to express traits in offspring?<br />Two alleles from its parents-either two alleles for tall stems, two alleles for short stems, or one of each.<br />
Human Genome Project<br />1.When did the project start and how did scientists hope to use this information?<br /> Started in 1990 <br />One of their goals was to identify all the approximately 20,000-25,000 genes in human DNA.<br />2. What are the implications of the Human Genome project in regards to Ethical, legal and Social implications?<br />Some of their implications were:<br />Examine issues surrounding the completion of the human DNA sequence and the study of human genetic variation.<br />Examine issues raised by the integration of genetic technologies and information into health care and public health activities.<br />3. How did the human genome project change current laws such as GINA?<br />GINA now protects Americans from discrimination based on information derived from genetic tests.<br />
Genetic Disorders<br />1.Compare and contrast the three different types of genetic disorders:<br />1.single gene disorder : Albinism, the lack of pigmentation in skin, hair, and eyes, is also a Mendelian human trait. Albinism, the lack of pigmentation in skin, hair, and eyes, is also a Mendelian human trait.<br />2. chromosome abnormalities:. A common abnormality is caused by nondisjunction, the failure of replicated chromosomes to segregate during Anaphase II. A gamete lacking a chromosome cannot produce a viable embryo. Occasionally a gamete with n+1 chromosomes can produce a viable embryo<br />3. multifactorial disorder: Schizophrenia is a complex illness thought to be caused by a number of genetic and environmental effects: Current research suggests that the causes of autism spectrum disorders (ASD) are multifactorial and include both genetic and environmental factors.<br />2. How can genetic counseling help perspective parents who have a genetic disorder regarding future children? It can help because the counseling will give them advice and it will tell them if what they are doing is right.<br />3. How are karyotypes used to predict genetic disorders?<br />Karyotypes are pictures of homologous chromosomes lined up together during Metaphase I of meiosis. The chromosome micrographs are then arranged by size and pasted onto a sheet.<br />
Argument 1<br />Animal cloning is bad because if you clone it to make food the food might contain bad stuff.<br />The European Commission plans to ban animal cloning for food production as well as the use of cloned farm animals and the marketing of food from clones. "I believe that the temporary suspension constitutes a realistic and feasible solution to respond to the present welfare concerns," said John Dalli, Commissioner for Health and Consumer Policy. <br />
Argument 2<br />Cloning is a waste of valuable resources.<br />Scientists think it would be more productive to study the breeding behavior of animals, like the panda, to figure out how to get them to mate in captivity. "There are 40,000 vertebrate species on the planet and in most cases we don't understand how they naturally reproduce," says David Wildt, senior scientist at the Smithsonian's National Zoological Park. "When we do understand, we can often breed these animals using low-tech approaches.”Cloningis a waste of valuable research resources.<br />
Argument 3<br />Cloning is a risk to animals.<br />The vast majority of clones suffer from birth defects. They also suffer from painful disease, and the animals die before they grow and mature. You are putting animals in danger when you clone them.<br />
Argument 4.<br />Cloning an extinct Dinosaur is not possible.<br />The DNA that you think you can clone a dinosaur with will not be preserved enough for you to be able to clone a species that died out 65 Million Years ago. Also why would you want to make another Jurassic park.<br />
Conclusion<br />I don’t think cloning endangered or extinct species is good because a lot of things could go wrong with it. I support all of my arguments. I hope you like the presentation. <br />
