You are told that both parent plants in the P generation of the diagram below are homozygous. With this in mind, choose the most likely reason 100% of the F1 generation shows the phenotype for yellow pea seed color.       

Two pea plants (AABB x aabb) were crossed, with the following F2 results:    Non-recombinant 228 AABB Recombinant: 17 AaBb   Recombinant: 26 aaBb Non-recombinant: 60 aabb   From the information provided in the F2 progeny, calculate the recombination frequency (round to next whole %).
