I mean, your cousin will select the best veggies to sell, and the most marketable veggies' seeds to re-grow. Eventually, the rounder skin and other surface-appealing traits will dominate, and there is no way to tell if the DNA of those increasingly-nicer-looking veggies result in a taste worse than a misshapen one. Monsanto is in the same business as your cousin, even if your cousin is not so serious and business-focused, and is just doing it for pleasure and fun. They both still want the best-looking (marketable) fruits, unless your cousin explicitly selects the seeds of the best-tasting fruits in his crop, as opposed to the best-looking ones. Monsanto, instead of waiting for them to grow and pick out the best ones, creates the "best" ones artificially. Their end objective is the same.
