1. How does genetic drift affect human evolution? Discuss it and present possible evidences.
Do no just copy from somewhere, please.
Step by step
Solved in 2 steps
- 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.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. 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 discovery
- 29. Natural selection is the primary driving force of evolution, but there are other mechanisms at play as well. Define the following means and explain how they contribute to the process of evolution.1. Explain in 200 words how the Darwinian evolution can decrease or increase the frequency of an allele( or a more complex heritable trait, for that matter).Step 1 The branch of Biological Sciences that deals with the study of genome is known as Genomics. The genome is the complete set of genetic information present in an organism. As per the guidelines, the answers for the first 3 questions are being provided here. The student is requested to upload the remaining questions separately. Step 2 Question 1: GWAS or Genome-wide Association Study is a method for identifying the genes that are responsible for giving an organism its phenotype. This method is very useful because - • It provides information on the SNPs that need our attention in order to know about the genetic risk for a particular condition in an organism. • The SNP identification makes it possible to understand the mechanisms that might cause the genetic risk and also might provide a scope to clarify the differences between the alleles. • This method can find genomic variants that cause a particular trait or disease in an individual. GWAS can solve problems such as - Finding out…
- 92. In natural selection, what is being selected for (or against)? gene genotype phenotype species mutations that arise on a chromosome1. In 200 words, explain the role of variation in evolution.1. Present possible evidences that genetic drift affect human population. Discuss this evidences comprehesively. Do not just copy from somewhere, I need evidences that shows that genetic drift has a role in human evolution. Thank you!
- 1. Does genetic drift affect natural selection? Yes or No? Discuss and explain it thoroughly. Do not just copy it from somewhere, please.1-A common misconception of evolution is that it should naturally eliminate "harmful" alleles/mutations if they do not assist survival or reproduction. Explain why this is inaccurate and how these "harmful" mendelian alleles persist within the human genome. In your response, give an example of a mendelian allele that causes a "harmful" genetic disease that does not appear to have a beneficial component. 2 - Name an allele that is "harmful" in homozygote arrangements yet "beneficial" in heterozygote combinations (*hint: there is one really great example in the textbook!) 3 - Explain why removing variation (even rare forms) from the genome of a species makes it susceptible to extinction. 4 - Explain in your own words Mendel's two principles of inheritance (independent assortment and segregation).7. A burned body is found after a warehouse fire. You cannot obtain nuclear DNA suitable for testing, but you are able to obtain a sample of the person's mtDNA. What challenge will you encounter when trying to identify the person using mtDNA? Everyone has the same mtDNA so you won't be able to narrow identity down. mtDNA is most useful for information on traits like hair color so it won't narrow things down much. mtDNA only shows patrilineal lineage so it will only show the father's mtDNA. mtDNA is time consuming and expensive; not all labs have the capabilities to test this.
