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 tomorrow
Why is a random mutation more likely to be deleterious than beneficial?
With regard to mutations, what is meant by the terms“harmful,” “beneficial,” and “neutral”? Why it issometimes an oversimplification to consider a mutation aseither harmful, beneficial, or neutral?

- . In a population of 50,000 diploid individuals, what isthe probability that a new neutral mutation will ultimately reach fixation? What is the probability that itwill ultimately be lost from the population?arrow_forwardConsider 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?arrow_forwardOne unexpected result of the sequencing of the human genome was the finding that mutations in a single gene can be responsible for multiple distinct disorders. How do you think mutations in a single gene can have such diverse effects?arrow_forward
- What are the factors that influence the mutation rates of human genes?arrow_forwardIn most cases, the rate of synonymous substitution for a gene is higherthan the rate of nonsynonymous substitution. Sometimes, however, therate of nonsynonymous substitution is higher. When would you expectto see this? What might bring it about?arrow_forwardWhy Spontaneous Mutations Occurat a Very Low Rate?arrow_forward
- Can you explain silent, beneficial, harmful, and lethal mutations?arrow_forwardGiven what you read about the human genomein Chapter 13, would you predict that most mutations in humansare harmful, beneficial, or neutral?arrow_forwardYou have sequenced a few individuals in the population and found out that there are only two alleles in the population: one is GGGTCC and the other GGGTAC. You also knew that the DNA sequence encodes two amino acid residues. The mutation responsible for the difference is an insertion mutation a transition mutation nonsynonymous mutation a neutral mutation a silent mutationarrow_forward
