Genetic Information, Cures for Disorders and Diseases By : Danny Fusco Period 8 Mrs. Martinez
About Traits How are traits controlled by dominant and recessive alleles? Dominant traits, when present, will show over recessive traits. So if you show a dominant trait, you could be homozygous (purebred) or heterozygous dominant. If you show a recessive you can only be homozygous (purebred) recessive. How are traits controlled with co-dominant alleles? When you have a co-dominant trait it is neither dominant or recessive and they both show in the offspring. Explain how the alleles of two parents combine to express traits in offspring? When an someone reproduces, your parents genes
Human Genome When did the project start and how did scientists hope to use this information (what were the goals in the beginning)? The human genome project started in 1990. The goals were… ∙ identify all the approximately 20,000-25,000 genes in human DNA,
determine the sequences of the 3 billion chemical base pairs that make up human DNA,
store this information in databases,
improve tools for data analysis,
transfer related technologies to the private sector, and
address the ethical, legal, and social issues (ELSI) that may arise from the project.
What are the implications of the Human Genome project in regards to Ethical, legal and Social implications (address each of these in your explanation) How did the human genome project change current laws such as GINA (Genetic Information Nondiscrimination Act of 2008) On May 21st, President Bush signed into law the Genetic Information Nondiscrimination Act (GINA), which prohibits U.S. insurance companies and employers from discriminating on the basis of information derived from genetic tests. GINA passed both houses of Congress with a vote in the U.S. House of Representatives of 414 to 1. The bill had passed in the House twice before, most recently last year when the vote was 420 to 3. The U.S. Senate unamiously passed the current bill after compromises were reached on areas of disagreement that had held up its passage for several months.
Genetic Disorders Angelman syndrome Angelman Syndrome is a rare disorder, having neuro-genetic causes. The syndrom was first described in 1965 by Dr. Angelman. A syndrome is a based on group characteristics and manifest a specific condition. This syndrom can be described by an intellectual and evolutional delay, difficulty to speak, sleep problems, hand, laughter or just smiling and a happy appeareance. Canavan disease Canavan disease is a genetic disorder which produces gradual damage to nerve cells of the brain. This disease belongs to the category of genetic disorders named leukodystrophies. Leukodystrophies’ feature is myelin degeneration that is the phospholipid layer which protects nerve fibers. Color blindness Color blindness, or deficiency to perceive colors can be of genetic nature, but can as well appear because of brain, eye, or nerve damage, or because of contact with some chemicals products. In 1798, the English chemist John Dalton studied for the first time this aspect, that is why it is sometimes called daltonism.
Argument 1 (pros about disorders) Genetic researches for cures of disorders like Alzheimer disease or Down’s Syndrome is very important. First people who have Alzheimer disease may not be able to do things they used to. They might have trouble getting around the house. If we had more funds for genetic research we might eliminate Alzheimer disease completely. Wouldn’t you be happier if you knew you children and grandchildren weren’t going to have their lives run by Alzheimer disease. What about Down’s Syndrome? Doesn’t a Down’s Syndrome free America seem like a better choice, if we could than why not?
