Temple Grandin had some interesting thoughts on how single trait breeding can lead to adverse affects in her discussion on "Rapist Roosters", and how this relates to software[0]. It seems like this is also happening here.<p>Typically when single trait breeding leads to an adverse, undesirable affect (lack of taste), while the selected trait was obtained (in this case, possibly bigger size) breeders don't start from scratch by trying to isolate the desired trait without obtaining the undesirable trait. Instead, as in software, the breeders iterate by trying to remove the negative trait, complicating the hybrids and possibly more unknown adverse traits. It seems like it might be wise to start from scratch in some cases and keep it simple, rather then make hybrid species whose lineage can be difficult to trace.<p>[0]: <a href="https://books.google.com/books?id=aMVmhqpILOAC&printsec=frontcover&source=gbs_ge_summary_r&cad=0#v=onepage&q&f=false" rel="nofollow">https://books.google.com/books?id=aMVmhqpILOAC&printsec=fron...</a> page 70
