Consider the evolutionary impact of the daf-18 mutation on populations of C. elegans. Discuss whether this mutation would be advantageous and if not, propose conditions under which these conditions could be advantageous.
Homework Answers
The impact of daf-18 mutation on populations of C. elegans is that it will pose a problem in the normal development and thus decrease the life extension of the worms.It will also the daeur larva formation that takes place constitutively by daf-2 and age-1 mutants.This mutation could be advantageous as it prevents the mutant worms from coming with contact with food containing NaCl.

2. Consider a gene with a particular function. Mutation X and mutation Y cach cause defects in the function of the encoded protein, yet a gene containing both mutations X and Y encodes a protein that works even better than the original protein. The odds are exceedingly small that a single mutational event will generate both mutations X and Y. Explain a simple way that an organism with a mutant gene containing both mutations X and Y...

Read just the long paragraph below and explain in your words the hypothesized evolutionary processes (note, more than one are in play) proposed to remove slightly deleterious alleles from the gene pool. Keep in mind the importance about balance between mutation rates and the consequences to individual fitness. "At first sight, it appears paradoxical that nearly neutral mutations in essential immune genes will be efficiently removed from the species’ gene pool despite having no easily discernible impact on the immune...

Review Questions BIOL 260: Chapters 8-10, 13, 19 1. Consider a mutation involving the deletion of either 1, 2, or 3 nucleotides in the DNA of a bacterium. Which of these mutations (ie., deletion of 1, 2, or 3 nucleotides) would likely have the LEAST impact on the organism? Why? Include in your answer a comparison with the other two options to justify your reasoning. Think carefully about the impact each mutation would have on the ultimate protein coded for...
