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...
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...
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...
Ever since humans began to grow their own food thousands of years ago, we have been struggling to find ways to make our crops grow bigger and better. In recent centuries though, science has made great improvements in the field of agriculture. This started with Robert Blakewell, an English farmer ...
Seems like somewhat of a cold notion to consider that these are some of the first words the doctor delivering your baby might speak after his birth. However, with the ever-growing technology and genetic know-how we see in the news today, it is certainly likely to assume that someday we will all be ...
1. Introduction The issue of engineered foods or genetically modified foods has raised debate and concern in the modern world. In essence the argument against engineered food is that the natural value and content of the foods has been interfered with and that they present a health risk to the p...
An article published on April 25, 1953 in the science journal Nature written by scientists James Watson and Francis Crick, modestly suggested a model for the structure and replication of the DNA (refer to picture 1), the face of science changed forever (Aldridge, 8). The evolution of technology has ...
 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...
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...
Implications of Neanderthal-Homo Sapiens Hybrid from the Abrigo do Lagar Velho (Portugal) In a recent excavation at Abrigo do Lagar Velho in Portugal, Duarte et al (1999) unearthed what was later to be recognized as early human skeletal remains which pointed to interbreeding between Neandert...
