6. 3 types of artificial selection

   • genetic modification, selective breeding, gene therapy

7. Selective breeding, gene therapy, genetic modification definitions

   • gene therapy
     • (Selective breeding)
       • genetic modification
         • when you go and replace genes that are not faulty and change them 1 pro is being able to solve world hunger 1 con is the animals they may modify could be under stress
       • choosing parents with particular characteristics to breed together and produce offspring with more desirable characteristics 1 pro is new varieties may be economically important by producing more or better quality food.1 con is it may create genetic deficiencies
     • the process of fixing faulty or defective genes 1 pro is being able to cure cancer 1 con is if gene therapy gets to a cell that has no issues that cell will become faulty as well
