scientist? Why is the breeder's notebook more important to the biologist 

 than the desirable fruit he may produce? 



10. A breeder has two varieties of apple trees. One bears sweet green 

 apples and the other sour red ones. He discovers that he would have a 

 market for sweet red apples. What could he do about it? Would he be 

 sure of success? Can you illustrate possible results by diagram? 



1 1. Plant breeders have advantages over animal breeders. Can you state 

 five distinct reasons wh^' the plant breeder could make more progress 

 than the animal breeder? 



12. Read about plant breeders in De Kruif's Hwiger Fighters , and 

 write a report. 



13. A plant breeder nowadays can take a patent on some new "crea- 

 tion" if it can be propagated vegetatively. Discuss the desirability and

 will give you information. 



Further Activities in Biology 



1. If you have a garden and are ready to carry a long experiment 

 through to completion you can do breeding experiments of your own. 

 Careful records are all-important. You can also learn to make grafts. Ask 

 your teacher for help. 



2. Many newspapers give descriptions and pictures of the many breeds 

 of dogs. Make a chart placing together the dogs that are most similar. 



3. Seed catalogues often give information on improved types. Write for
