Genetically Vigorous Populations Essay - 1508 Words

Genetically Vigorous Populations Paper Megan Lade University of Phoenix (Online Campus) Niladri Sarker Introduction into Genetic Diversity Genetic diversity provides a species with its form and function. A species genotype refers to their genetic code; what their cells are going to be used for – hair cell, eye cell, muscle cell, etc. A species phonotype refers to the way in which that species gene will be expressed – blonde hair, blue eyes, large muscle tone; which significantly impacts the success of that individuals genes. Without genetic diversity among populations the gene pools would be very limited, which gives way to a rise in mutations and inevitably the end of a species. â€Å"Genes regulate body size, shape,†¦show more content†¦Ã¢â‚¬Å"As biological novelties to the ecosystems, GM crops may potentially affect the fitness of other species, population dynamics, ecological roles, and interactions, promoting local extinctions, population explosions, and changes in community structure and function inside and outside agro-ecosystems† (Gertsberg, 2011). Population Management Population management is dependent upon the carrying capacity of a population. The carrying capacity of a population is described as the maximum population size of a species that the environment can sustain given all necessary items such as food, water and habitat are available. Genetic diversity is a key value when discussing population management as the more diverse a population is, the more resistant that species will be to environmental changes and disease. Over population, exceeding that population’s carrying capacity can cause starvation, loss of habitat and death. Controlling food sources and other natural resources can help control a population’s numbers; which further increases the opportunity for genetic diversity among healthy species. Another way to control invasive species, mostly plant species, is via controlled fires; alternatively the reintroduction of natural predators also controls populations. As with everything in life, we can h ave ‘too much’ – finding the happy medium in the points above is key to successful population management. The Texas Parks and Wildlife Commission has a very detailed populationShow MoreRelatedEssay on Cons of Genetic Modification of Plants 1024 Words   |  5 PagesIn our everyday lives we have a substantial need for food. Everyone on planet earth needs food to survive from day to day, so engineers have begun mutating plants and crops to create a better source of nutrition to the population. Scientists are pushing the boundaries in order to create the most bountiful crops and, in turn, healthier people. Imagine what could happen if there were larger harvests, more succulent fruits and nutritious vegetables. Our imagination can run wild with the endlessRead MoreWhat Are Genetically Modified Foods?1236 Words   |  5 PagesWhat are genetically-modified foods? The term GM foods or GMOs (genetically-modified organisms) is most commonly used to refer to crop pla nts created for human or animal consumption using the latest molecular biology techniques. These plants have been modified in the laboratory to enhance desired traits such as increased resistance to herbicides or improved nutritional content. The enhancement of desired traits has traditionally been undertaken through breeding, but conventional plant breeding methodsRead MoreFarmers Getting Played A Monopoly Essay1719 Words   |  7 PagesMonsanto is an international corporation based out of the United States of America. They are accredited with most of the genetically modified crops in the country today. In 1996, Round Up Ready soybeans were introduced to the farming community. (Brown) This was main introduction of GMOs into agriculture. By 2003, Monsanto already accounted for ninety-percent of the world genetically modified crops. (Brown). The use of the crops has steadily increased since and now threaten farmers greatly. The problemRead MoreEssay on The Validity of the Theory of Evolution1539 Words   |  7 Pagesinstance, birds beaks have evolved from species to species based on the diet needs and the food available in each region over the decades. A species population may change over time due to genetic changes which these genetic changes often include visible differences, and different instincts to adapt to a different habitat. Species change genetically over the years due to reproduction in the habitat, just as the bird developed distinctly to attain food easier in different habitats. Species of animalsRead MoreA Research On Selective Breeding Essay2193 Words   |  9 Pageswill have different alleles to each other but have the same genes, the combination of all the possible alleles in the population is known as the gene pool. There is variation in alleles and phenotypes within the gene pool of a population due to segregation, independent assortment and crossing over between homologous chromosomes during meiosis causing the offspring to be genetically identical to its parents. In nature different environmental factors act as selection pressures for organisms and overRead MoreAnalysis Of Oryx And Crake By Margert Atwood Essa y1171 Words   |  5 Pagesevolution and these current trends in science involving gene splicing could result in a dystopian future for humanity. However, the pharmaceutical companies started to go beyond creating medicines that would benefit humans. Their expansion of genetically modifying animals raises concerns as to what exactly comprises nature (Quimbaya). Crake and other scientists began experimenting with the idea of creating the ideal or perfect human. Crake believed that lack of sex in people’s lives went hand inRead MoreWhy We Get Fat And What You Do About It Published By Gary Taubes1073 Words   |  5 Pagespassed through the Pima lands, it was recorded that they were in fine health with an abundance of food. In fact, the Pima peoples had so much food that during the Gold Rush, they supplied food to California. This all changed in the 1870s. The Pima population started to live in famine. They began relying on government rations, and then obesity started popping up. Years later, almost all of the Pima people were obese. They were eating an abundance of food before and weren’t fat, which went against t heRead MoreA Short Note On Diabetes Mellitus Type II1041 Words   |  5 Pages(Diabetes Mellitus,2005-2016). The impact on the human physiology is by insufficient production of sugar (insulin) in the bloodstream which then over the time damages to other organs. According to Public Health Agency of Canada, 90% to 95% of Canadian population are diagnosed with diabetes, especially with Type II diabetes (PHAC, 2016). It is statically proven that in 2008-09, approximately 2.4 million Canadians from the age group of one year and older are diagnosed with diabetes. In addition, 6.4% of femalesRead MoreA Short Note On Diabetes Mellitus Type II1039 Words   |  5 Pages(Diabetes Mellitus,2005-2016).

It is the varying genetics that each species carries that makes it different and â€Å"unique†. Biodiversity is important, not only in evolution, but in survival; when sometimes those terms can mean the very same thing. Interestingly, biodiversity can mean a variance in the life itself – or within the genetics of a species. In keeping breeding
