Population: a localized group of individuals that belong to the same biological species, capable of interbreeding and producing viable offspring. c. Population genetics: the study of how populations change genetically over time. d. Gene pool: the total aggregate of genes in a

The human genome is constructed of four simple chromosomes, each of which is represented by a single capital letter; G, A, C, and T. These simple chemicals are the building blocks of life, and act as the blueprints for one of the most complicated biological structures in the known universe; the human. Strands of these chromosomes billions of letters long provide a uniqueness that guarantees individuality in a swiftly growing world. Is not individuality after all one of the most highly acclaimed

AP Biology: Unit 3: Cell Division & Genetics: Virtual Lab #4: Punnett Squares Instructions 1. Open the Virtual Lab: Punnett Squares: http://www.mhhe.com/biosci/genbio/virtual_labs_2K8/labs/BL_05/index.html 2. The virtual lab simulation will be on the right side of the screen, and the “Question” column will be on the left side of the screen. 3. Click on the TV/VCR and watch the video. 4. Read the background information in the Question Column under “How can Punnett Squares help predict

“Just as the success of a corporate body in making money need not set the human condition ahead, neither does every scientific advance automatically make our lives more meaningful'; (Wald 45). These words were spoken by a Nobel Prize winning biologist and Harvard professor, George Wald, in a lecture given in 1976 on the Dangers of Genetic Engineering. This quotation states that incredible inventions, such as genetic engineering, are not always beneficial to society. Genetic engineering is “altering

has two sets of character determinants, or genes (Stableford 16). For instance, in regards to eye color, a child could receive one set of genes from his father that were encoded one blue, and the other brown. The same child could al so receive two brown genes from his mother. The conclusion for this inheritance would be the child has a three in four chance of having brown eyes, and a one in three chance of having blue eyes (Stableford 16). Genes are transmitted through chromosomes which reside

Muscles strong enough to flip over a tank. Eyes that see the night as clear as day. Perfect photographic memory. These sorts of human enhancements are found in video games like Halo 3 and other science fiction media. It seems that an average human of today will not be enough for the future. The demand for human enhancement is widely present. Professional sports leagues allow certain drugs like caffeine to be used. Sports players are often caught abusing steroids to gain an edge over the other players

Gene Therapy is Revolutionizing Medicine "We used to think that our fate was in our stars, but now we know that, in large measure, our fate is in our genes, "quotes James Watson. This fate that Watson is talking about is contained in our genes, and deals with a new technique, gene therapy. Gene therapy is revolutionizing the world of medicine. Many physicians are predicting that in twenty years gene therapy may change the practice of medicine from a treatment-based to a prevention-based practice

genetically modified before birth, (as an embryo) to change their sex, looks or possibly even personality! Since the DNA code was cracked a couple of years ago, it has been made possible to change a human embryo by injecting genes into it. These injected genes can change the sex, looks and personality of that particular child when he / she is born. For example, you can currently choose the sex of your child in the USA although it costs a hefty $ 2500. Are these designer

environment preserving activities, we could still greatly damage our ecosystems. The cause of this is simply because of the technological pollution caused by the use of genetically engineered crops. These plants are different in that they have had genes inserted into their genetic code, giving them added traits which are suppose to aid them in producing greater yield or defending against insects and disease, amongst other benefits. But their benefits are short-sighted; people around the

The genetic technology revolution has proved to be both a blessing and a blight. The Human Genome Project is aimed at mapping and sequencing the entire human genome. DNA chips are loaded with information about human genes. The chip reveals specific information about the individuals’ health and genetic makeup (Richmond & Germov 2009).The technology has been described as a milestone by many in that it facilitates research, screening, and treatment of genetic conditions. However, there have been fears
