CRITICAL THINKING QUESTIONS n a separate shee t of paper, answer the following questions. 1. Describe the circumstances under which mutation will have a re al evolutionary effect. Describe the circumstances under which mutation will not have a real evo I evolutionary effect discussion. Describe a hypothetical scenario of sure to describe each of the key elements (such as how the trait varies in the into resource competition, and how the trait frequency changes over multiple 2. This question may be completed independently or as a group natural selection for a trait Be population, how the trait factors generations) each of 3. This question may be completed independently or as a group dis cussion. Describe a hypothetical scenario of the founder effect for a trait where substantial genetic variation is lost (causing a genetic bottleneck). Be sure to and how the trait frequency changes over multiple generations). such as why the founder effect event occurs, why genetic information is lost, 4. This question may be completed independently or as a group discussion. Describe a hypothetical scenario of gene flow for a trait. Be sure to describe each of the key elements (such as the trait frequency in the two populations prior to gene flow, why gene flow occurs, and the consequences of the gene flow event in future generations)Explanation / Answer
Q1) Since all cells in our body contain DNA, there are lots of places for mutations to occur; however, some mutations cannot be passed on to offspring and do not matter for evolution. Somatic mutations occur in non-reproductive cells and won't be passed onto offspring. For example, the golden color on half of this Red Delicious apple was caused by a somatic mutation. Its seeds will not carry the mutation. The only mutations that matter to large-scale evolution are those that can be passed on to offspring. These occur in reproductive cells like eggs and sperm and are called germ line mutations.
