Question
  1. Trihybrid Cross: Several testcrosses have revealed the rate of recombination for the following genes which are KNOWN TO BE LINKED:

 

k-m       0.30

k-l         0.76

l-m        0.50

 

What is the order of the three genes and why is the frequency of recombination between the closest pair of genes not equal to the recombination rate between the two genes farthest apart? (0.8 > 0.76)
