Two genes on chromosome 7 of corn are identified by the recessive alleles gl (glossy), which determines glossy leaves, and ra (ramosa), which determines branching of ears. When a plant heterozygous for each of these alleles was crossed with a homozygous recessive plant, the progeny consisted of the following genotypes:
Gl ra 88 gl Ra 103
Gl Ra 6 gl ra 3
a. What is the frequency of recombination between these genes?
