Quizplus · Accepted Answer

M.genitalium has the smallest genome size and has undergone extensive gene loss during its evolutionary history, particularly in genes involved in biosynthesis of amino acids. Therefore, the type of gene that has been lost the most in M.genitalium is biosynthesis of amino acids.
