#Unit 8. Inheritance Biology
  1. Chance of crossing over is 100% and  recombinational frequency will be the 50% 
  2. chance of crossing over will be 50% and recombinational frequency will be the 25% this  is the case of incomplete linkage
  3. Chance of crossing over is 50% and  recombinational frequency will be the 100% 
  4. chance of crossing over will be 50% and recombinational frequency will be the 25% this  is the case of incomplete linkage
