So the question is,
A mutant in the Columbia ecotype of Arabidopsis, pass1, was mapped relative to marker A. For homozygous F2 pass1 plants from a Columbia © x Landsberg (L) cross the results for marker A were 60 CC, 10 CL, and 4 LL. Calculate the genetic distance (cM) between marker A and pass1.
I used the equation: Distance = (Number of recombinant chromosomes)/(Recombinant chromosomes+parental)) x 100 and got 13.51%, however, this does not seem to be the correct answer. Can anyone tell me what I have done wrong here?
This is a multiple choice question and so the answer should be either: 5.4, 18.9, 12.2 or 9.5.
