1. Does genetic drift affect natural selection and does natural selection affect genetic drift. Explain it thoroughly and in an understable way.
Do not just copy it from somewhere.
Step by step
Solved in 2 steps
- 1. Does genetic drift affect natural selection? Yes or No? Discuss and explain it thoroughly. Do not just copy it from somewhere, please.1. Describe the key components of Natural Selection and explain how the process of Natural Selection can lead to biological change 2. Describe the scientific discoveries of Gregor Mendel and how they help to support Darwin's Theory Of Natural Selection You can research Darwin's Theory of Evolution By Natural Selection to find the answer and the same with Gregor Mendel's scientific discovery1. How do we measure and define evolution? 2. Evolution occurs: 1. at the level of the individual. 2. in traits. 3. in a single generation. 4. only at the phenotypic level. 3. The only source of entirely new genetic material is: 1. natural selection. 2. mutation. 3. recombination. 4. genetic drift. 4. Which of the following is not a key component of natural selection? 1. Traits for strength and vitality are favored over other traits. 2. Random variation exists for every trait in a population. 3. There will always be competition for resources. 4. Those with advantageous traits will outreproduce others. 5. The founder effect is a specific type of: 1. gene flow. 2. meiosis. 3. genetic drift. 4. mutation. 6. When a substantial amount of genetic variation is lost, we call it a: 1. genetic die-off. 2. gene flow. 3. genetic bottleneck. 4. gene dam. 7. When two previously isolated populations begin interbreeding and exchanging genes, we call it: 1. genetic drift. 2. founder effect. 3. incest.…
- 1. Definitions of phenotype, genotype, allele, gene, microevolution, macroevolution 2. Know that in humans, most of the genetic variation is observed within populations, and know why that is. 3. Know the 4 processes of evolution (3 neutral + natural selection) 4. Know that evolution isn't progressive and doesn't necessarily lead to more complexity 5. Know that evolution can lead to traits that decrease survival (ex: sexual selection)1. What could be the possible roles of genetic drift in human evolution? Discuss it and show possible evidences for each role. Do not just copy it from somewhere, please.What is the main factor that differentiates genetic drift from natural selection? 1. Genetic drift occurs due to human influence, while natural selection is natural. 2. Genetic drift is random, while natural selection is based on advantageous traits. 3. Genetic drift is a mechanism of evolution, while natural selection is not.
- 1. How does genetic drift affect human evolution? Discuss it and present possible evidences. Do no just copy from somewhere, please.Is natural selection random with respect to fitness? I know that genetic drift, gene flow and mutations are random with respect to fitness, but I wasn’t sure about natural selection. Thanks for your help.1. Why do you think it is necessary for there to be variation in a population in order for evolution by natural selection to occur? 2. Why is it necessary for traits to be inherited for evolution to take place? 3. If a population is already well adapted to its environment, will most mutations be helpful or harmful? Explain.
- 1. What could be the possible roles of genetic drift in human evolution? Discuss it thoroughly and present possible evidences for these roles. Do not just copy it from somewhere, please.1.) Natural Selection: Of the three genotypes (AA, Aa, and aa), which of the three genotypes will be selected for under the current conditions? In other words, which of the three genotypes will increase in frequency? What if medical science were able to hold off the effects of AIDS for indefinite periods of time so that it became common for people with AIDS to live long enough and well enough to have children. What would this do to the frequency of the resistance allele and the incidence of AIDS? Support your answer. 2.) Even though anti-HIV drugs may prevent evolution towards resistance, can you justify not using anti-HIV drugs if they are available? Your response should consider scientific and ethical perspectives.Explain genetic drift (and it’s various types) as a force of evolution (how does genetic drift contribute to biological change?)
