EXERCISE 2 - Measuring Recombination in a Test Cross

2. The Colored-kernel phenotype (C) is dominant to colorless (c) in maize. A backcross was done (CcSs x ccss) and kernels scored for the colored phenotype. DNA was extracted from these backcross offspring and analyzed by Southern hybridization, using the Shrunken locus probe as above. The results for 25 individuals looked like this:


Calculate the linkage between the C and S loci.
