Which statement best describes how mutations are related to evolution? question 3 options: there is not a strong relationship between mutations and evolution. natural selection causes evolution, which causes more mutations to appear in the dna of the species. mutations are changes in dna that produce weaker organisms that die, so these are eliminated by evolution. mutations lead to new genes, which may have an advantage over the old forms, causing the species to evolve.

Mutations lead to new genes, which may have an advantage over the old forms, causing the species to evolve.

Mutation assumes a significant job in evolution. A definitive wellspring of all hereditary variety is a mutation. It is significant as the initial step of development since it makes another DNA succession for specific quality, making another allele.

Recombination additionally can make another DNA succession (another allele) for a particular quality through intragenic recombination. Mutation going about as a developmental power independent from anyone else can possibly cause huge changes in allele frequencies over exceptionally significant stretches of time.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
