The table below shows the progeny of a test cross of a heterozygote (JjBbRr). Each row shows the number of progeny that inherited each combination of alleles from the heterozygous parent. You've already determined the gene order (B is in the middle) and labeled each type of progeny. Using this information, what is the recombination frequency between J and B?
