In this lab, we explore the effects of natural selection on a snail population in two separate environments. Natural Selection is a theory first introduced by Charles Darwin, who suggested that populations produce a large number of offspring which leads to limited resources for survival. This theory states that individuals who are best adapted to the environment are the ones who survive and live on to reproduce and pass on their genetic information to offspring. The adapted traits would accumulate and change the population over time. The environment determines which traits are most evolutionary desirable to an organism. If a population should move or should the environment change, a different set of traits would be the most advantageous†¦show more content†¦Results In the grassy habitat, the green allele frequency among the snail populations steadily increased as the brown allele frequency decreased. The BB and Bb genotype frequencies increased while the bb genotype frequenc y decreased. The green snail phenotype increased while the brown snail phenotype decreased. In the forest floor habitat, the brown allele frequency among the snails increased as the green allele frequency decreased. The BB and Bb genotype frequencies decreased while the bb genotype frequency increased. The brown snail phenotype increased while the green snail phenotype decreased. Discussion This lab is a fundamental example of Darwin’s theory of Natural Selection because it clearly shows the changes in population that were created because of traits that were considered to be the most advantageous in certain environments. These desired traits were then passed down to subsequent generations leading to a change in the overall genotype and phenotype frequencies of the population. This lab investigation also demonstrated the importance of environment in the role of natural selection. If the brown snails that lived in the grassy field had moved to a different location or had the environment changed, such as the grass in the habitat dying and turning brown, then their survival rates would have been much different.Show MoreRelatedMarketing Management130471 Words   |  522 Pagesreasons why marketing is considered important in this era To assess the various marketing approaches and principles 3. MARKETING MANAGEMENT: Marketing has evolved into a very important functional area in management basically due to the increasing supply and lower demand over the years. This is primarily through the competitive intensity in every sphere of the market. When competition increases, as you know, every firm wants to be heard in the market.
