- In Genetic Variation, If people have a similar genetic makeup, why do weu use DNA to understand or determine whether suspects are innocent or guilty of a crime.How can you use this piece of information to help you explain to your friends what is the significance of mutations in the emergence of new genetic properties (alleles) that may result (or not) in new phenotypic characteristics? (Recall that not all SNPs affect phenotype.)Discuss the role of mutation in the origin of genetic polymorphisms. Suppose that a genetic polymorphism involves two alleles at frequencies of 0.45 and 0.55. Describe three different scenarios to explain these observed allele frequencies. You can propose that the mutations that produced the polymorphism are neutral, beneficial, or deleterious.
- _______________ is the chance that a specific base pair will change, while _______________ is the chance that a gene will have a function-altering mutation. Group of answer choices Mutation frequency; mutated-gene rate Mutation rate; mutation frequency Mutation frequency; mutation rate Mutation rate; mutated-gene frequencyConsider a recessive condition where 40% of the affected individuals pass away by the age of 10 but those that survive to adulthood are just as likely to have children as the general population. What must the new mutation rate be if the incidence of the disorder is 1/10,000 to maintain a consistent incidence across generations? Answer format: Fraction - #/#Sickle cell anemia is a disease caused by a mutation at the genotypic level. A person with two copies of the gene has the disease, but a person with one copy of the gene does not have the disease. The diagram shows how this mutation affects an organism. Use the image to answer the question. The mutation causes the deformity of the red blood cell, the component of blood that carries oxygen throughout the body. The deformed cells can clump together and can clog blood vessels. The parasites responsible for the sickle cell condition are killed in the deformed red blood cells. In which type of environment would carriers of the disease be naturally selected for? A. low altitude B. high altitude C. low population of parasites D. high population of parasites
- DNAs are an organism’s blueprint. The code for any trait/character is stored in it. What allows it to function as such?1. What is an allele? 2. What is a point mutation? 3. How are point mutations related to alleles? Use these sites to find the answer please: https://www.britannica.com/story/whats-the-difference-between-a-gene-and-an-allele http://rosalind.info/glossary/point-mutation/Imagine you've been offered a deal from a genomics company. You can get a free genome sequence – an analysis of all your DNA that includes a report of your ancestry, traits and a medical profile. The medical profile tells you about diseases for which you have a low risk of getting, and also those you have a high risk of getting. Are you interested? Why or why not?
- The delta-32 mutation, a recessive gene, gives humans protection from HIV infection. The allele frequency in a town in Sweden is 20%. What percent of the population have two copies of the gene and are therefore immune to HIV? What percent of the population are less susceptible to the disease since they are heterozygous?Most of the genetic information we will get from our genome will not be hard evidence that we will or we won’t get a disease but is rather only probabilistic evidence. a. What does this mean? b. Why might knowing a single gene not tell you if you will get a particular condition?Why we stilldon’t have an accurate count of the number of genes. ?
