a) A dihybrid plant with incomplete linkage on test cross may produce how many types of plant?
b)A test cross of \(\sf F_1\) flies +a/+b produced the following offspring
++/ab = 9%
ab/ab = 9%
What will be the distance between linked genes?

Distance in map units, also called centi-Morgans, is the same as the percent recombination. Based on the genotype of the F1, +a and +b are parental while ++ and ab are recombinant, meaning that there was a break between a and b during crossing over. 9+9 (sum of recombinants)/100 (sum of progeny)= 18/100= 18% or a distance of 18 map units or centi-Morgans.
But can you tell me the arrangement of genes on the chromosome, cis or trans?
