plz help 1. What would be the percentage of the non-singing trait in female birds in Generations 4 and 5 if this pattern continues? (5 points) 2. In which generation will there be almost 100% non-singing females if there are no changes in the birds’ environment and interactions? (5 points) 3. In what possible scenario would the female birds evolve to having the singing trait? (5 points)
