- Consider the following estimates:(a) There are 7 x 109 humans living on this planet.(b) Each individual has about 20,000 (0.2 * 105) genes.(c) The average mutation rate at each locus is 10-5.How many spontaneous mutations are currently present inthe human population? Assuming that these mutations areequally distributed among all genes, how many new mutationshave arisen in each gene in the human population?If the rate of mutation is 10–5 per gene per cell generation, how many new mutations per gene would you expect in a population of 1 million bacteria?What is genetic flow? A) Genes changing due to mutation B) Random loss of genes in a small population C) Movement of genes between different populations
- If the rate of mutation is 10–5 per gene, how many new mutations per gene would you expect in a population of 1 million bacteria?Which type of mutation doesnt affect the ability of an organism to pass on its alleles to the next generation? a) beneficial mutation b) positve mutation c) deleterious mutation d) neutral mutation I have also attached a question down below. Please let me know if there is are any mistakes as I have a test tomorrowBetween gene mutation and structural mutations, which of the two types of mutation would likely persist in the population?
- Between gene mutation and structural mutations, which of the two types of mutation would likely persist in the population? Explain.If a population is already well-adapted to its environment, will most mutations be helpful or harmful? Explain.Some populations change noticeably in form within a hundred years. If only one gene in every 200,000 mutates and if most mutations are harmful, how is such change possible?
- A new beneficial mutation arises in a population of bacteria (haploid microbe) with a population size of 100,000. Individuals without the mutation have a 1% reduction in survival relative to individuals with the mutation. How many generations do you expect it take for the allele to reach fixation?In your group, consider the following statement: "Mutations are random, natural selection is not." What does that statement mean?Why is a silent mutation ignored by natural selection?
