Two mutations that affect plaque morphology in phages $(a^{-}$ and $b^{-}$ ) have been isolated. Phages carrying both mutations $a^{-}$ $b^{-}$ are mixed with wild-type phages $(a^{+} b^{+})$ and added to a culture of bacterial cells. Once the phages have infected and lysed the bacteria, samples of the phage lysate are collected and cultured on plated bacteria. The following number ofplaques are observed:What is the frequency of recombination between the $a$ and $b$ genes?
