You decide to genetically map the order of 3 genes in you blue corn plant. From your crosses, you calculate the following recombination frequencies: RF(a-b): 12.2% RF(b-c): 14% RF(a-c): 2% Based on these data, which of the following is the correct map ?

Let’s imagine that in corn plants, blue kernels (b+) are dominant to yellow kernels (b), and long leaves (l+) are dominant to short leaves (l).  You carry out a testcross between a plant heterozgous for both color and leaf length with a plant homozygous recessive at both loci. You obtain the following data from the cross: 965 wild type (blue,long) 944 (yellow, short) 206 (blue, short) 185 (yellow, long)  b+b l+l bb ll b+b ll bb l+l   What is the recombination frequency (RF) between the Blue Kernel and Leaf Length loci?
