Here were dealing with the G H and J genes Here is the perce
     Here, we\'re dealing with the G, H, and J genes. Here is the percent recombination between these genes you\'d see from a trihybrid testcross. Based on this information, select the option below that has the correct gene map. H rightarrow g 5% g rightarrow j 20% h rightarrow j 25%  
  
  Solution
A centimorgan (cM) is a unit that describes a recombination frequency of 1%.
option 2 (C) is correct
J G H
1--------------------------------------------------------------1------------------------------1
20% / 20 mu 5% / 5 mu
1----------------------------------------------------------------------------------------------1
25% / 25 mu
