Population Genetics and the Hardy-Weinberg Theorem Introduction When thinking of population genetics there are two key names that mark important moments in the history of science. Darwinian selection, which includes Darwin's four postulations one: stating that individuals within...
Ethical Concerns of Classical Breeding and Genetic Engineering " You can stop the splitting of an atom; you can stop visiting the moon; you can stop using aerosols; you may even decide not to kill an entire population by the use of a few bombs, but you cannot recall a new form of life.&q...
Interest is growing in the application of evolutionary and genetic behavioral ecological theory to problems of human lifetimes age specific fertility and mortality, population growth, and emerging population-environment interactions. An understanding of human evolution, particularly the effects of e...
Bioethics and Genetic Engineering By the year 2025, the world's population will be approximately 7.4 billion people and 2 million clones. What seems like something from a bad science fiction movie could, indeed, be a reality based on how quickly technology is growing in the area of...
Science is a creature that continues to evolve at an ever-increasing rate. The transformation from tree shrew, to ape, to human far exceeds the time for the transformation time from an analytical machine, to a calculator, to a computer. However, science, in the past, has always remained distant....
Too often, when the term genetic engenering is uttered, people envision a world of geneticly "perfect" people where thouse who are normal are looked down on by genetic supermen. The fact that this vision could not be further from the truth does not dissuade the nay sayers from vemonently dissparai...
Molecular Biotechnology in Our Life If you have had a can of soft drink, ate a fruit, or took some head ache medicine this morning - then it's very likely you have used a genetically enhanced product. Genetics is a part of biotechnology that manipulates biological organisms to make products...
Biotechnology is a powerful, controversial and critical topic dealing with disease, genetics, and the use of microorganisms or other biological substances to make industrial or manufacturing processes. Biotechnology has spawned many new ideas and discoveries to benefit society. It plays a part in he...
The Positive Effects of Gene Altering Since the beginning of the human race, we have been looking. We have been looking for ways to make our lives healthier, more comfortable, and happier. In the beginning it was simple rocks, plants, and fires. As our technology advanced so did the comfort of...
Single nucleotide polymorphisms (SNPs) are DNA sequence variations that occur when a single nucleotide is altered. A SNP might change the DNA sequence from AAGGCTAA â ATGGCTAA. SNPs occur every 100 to 300 bases. SNPs can occur in both coding and noncoding regions of the genome. Some SNPs have...
 To Clone or Not to Clone? In February 1997, when Dr. Ian Wilmut and his team of scientists in Scotland astonished the world by announcing that they had successfully cloned a sheep, it sparked an international debate. Since the invention of Dolly, scientis...
Evolution is the complex process by which living organisms originated on earth and have been changed and modified through changes in form and function. The earliest known fossil organisms are single-celled forms that are kind of similar to modern bacteria, which date back from about 3.4 billion year...
TIM VINES: FIRST YEAR REPORT ASSORTATIVE MATING IN A Bombina HYBRID ZONE INTRODUCTION A hybrid zone will be formed when diverged populations meet and interbreed, and give rise to viable hybrids. When these are also fertile, further generations of backcrossing can produce a wide range of...
Picture that there are two people who decide to have a child. They discussed and settled upon allowing nature to decide how their child will turn out. Time passed and once again they wanted another child, but this time they choose to let science do the deciding. They scheduled an appointment w...
Genetic screening, also known as preimplantation genetic diagnosis (PGD), is a newly emerging technology that has brought with it much controversy. PGD involves the in vitro fertilization of an embryo. "The embryos are allowed to develop to a 6 to 10 cell stage, at which point one of the e...
