Question: the allele for black noses in wolves is dominant over the allele fro the brown noses. There is no known selective advantage for one nose colour over another in wolves. If this remains true, which of the following statements is most liklely TRUE about the change in wolf nose colours re over many generations?Black noses will become more common than they are

Black noses will become more common than they are now
black noses will stay about the same frequency as now

Step 1Let's solve this population genetics problem step by step:
Step 2: Understand the Genetic Inheritance
- The allele for black noses is dominant over the brown nose allele - There is no selective advantage for either nose color
Final Answer
Explanation: When there is no selective advantage for a particular trait, genetic drift and mutation rates are typically too small to cause significant changes in allele frequencies over generations. The Hardy-Weinberg principle predicts genetic equilibrium under these conditions.
