What role do mutations play in genetic diversity?
Understand the Problem
The question is asking about the role of mutations in creating and maintaining genetic diversity within populations. It offers multiple choices that reflect different understandings of the relationship between mutations and biodiversity.
Answer
Mutations create genetic diversity by forming different gene versions, leading to unique individual traits.
Mutations play a crucial role in genetic diversity by creating slightly different versions of the same genes, called alleles. This genetic variation is essential for natural selection and evolution, leading to diverse traits in organisms.
Answer for screen readers
Mutations play a crucial role in genetic diversity by creating slightly different versions of the same genes, called alleles. This genetic variation is essential for natural selection and evolution, leading to diverse traits in organisms.
More Information
Mutations introduce new genetic combinations which can confer advantages, disadvantages, or neutrality to organisms, influencing survival and reproduction.
Tips
A common mistake is assuming all mutations are harmful. Many mutations are neutral or beneficial, providing a source of genetic variation.
