242 The Nature of Gene Mutations 



2. If you had two fruit trees that were identical except that in one 

 bud sports appeared rather frequently, which would you select as the 

 better for propagating nursery stock? Why? 



3. If it could be proved that somatic mutations were inherited, would 

 we have to revise our concepts of heredity and evolution? 



4. Two fruit trees are of the same variety, but one is grown in poor 

 soil and the other is grown under very favorable conditions. The second 

 produces a better yield, but when bud grafts are made from both trees, 

 those of the first produce better yields. Explain.
