Domesticated plants differ from their wild relatives in many ways, including

* lack of [[Shattering (agriculture)|shattering]] such as of cereal ears (ripe heads),<ref name="Purugganan Fuller 2009"/> loss of fruit [[abscission]]<ref name="Lenser-Theissen-2013"/>
* less efficient [[breeding system]] (e.g. without normal [[pollinating]] organs, making human intervention a requirement), larger seeds<!--e.g. wheat--> with lower success in the wild,<ref name="Purugganan Fuller 2009"/> or even sterility (e.g. [[Fruit#Seedless fruits|seedless fruits]]) and therefore only vegetative reproduction<ref name="Agusti citrus 2020">{{cite book |last1=Agusti |first1=Manuel |last2=Primo-Millo |first2=Eduardo |date=2020 |title=The Genus Citrus |url=https://www.sciencedirect.com/science/article/pii/B9780128121634000115 |publisher=Woodhead Publishing |pages=219–244 |isbn=978-0-12-812163-4}}</ref><ref name="Perrier banana 2009">{{cite journal |last1=Perrier |first1=Xavier |last2=Bakry |first2=Frédéric |last3=Carreel |first3=Françoise |last4=Jenny |first4=Christophe |last5=Horry |first5=Jean-Pierre |last6=Lebot |first6=Vincent |last7=Hippolyte |first7=Isabelle |display-authors=3 |title=Combining Biological Approaches to Shed Light on the Evolution of Edible Bananas |journal=Ethnobotany Research & Applications|date=2009 |volume=7 |pages=199–216 |url=http://journals.sfu.ca/era/index.php/era/article/download/362/231 |doi=10.17348/era.7.0.199-216 |hdl=10125/12515 |access-date=October 27, 2019 |archive-date=November 16, 2019 |archive-url=https://web.archive.org/web/20191116055142/http://journals.sfu.ca/era/index.php/era/article/download/362/231 |url-status=live |doi-access=free|hdl-access=free }}</ref>

[[Plant defense against herbivory|Plant defenses against herbivory]], such as [[thorns, spines, and prickles]], poison, protective coverings, and sturdiness may have been reduced in domesticated plants. This would make them more likely to be eaten by herbivores unless protected by humans, but there is only weak support for most of this.<ref name="Milla Osborne Turcotte Violle 2015" /> Farmers did select for reduced bitterness and lower toxicity and for food quality, which likely increased crop palatability to herbivores as to humans.<ref name="Milla Osborne Turcotte Violle 2015">{{cite journal |last1=Milla |first1=Rubén |last2=Osborne |first2=Colin P. |last3=Turcotte |first3=Martin M. |last4=Violle |first4=Cyrille |title=Plant domestication through an ecological lens |journal=Trends in Ecology & Evolution |publisher=Elsevier BV |volume=30 |issue=8 |date=2015 |doi=10.1016/j.tree.2015.06.006 |pages=463–469|pmid=26138385 |bibcode=2015TEcoE..30..463M }}</ref> However, a survey of 29 plant domestications found that crops were as well-defended against two major insect pests ([[beet armyworm]] and [[green peach aphid]]) both chemically (e.g. with bitter substances) and morphologically (e.g. with toughness) as their wild ancestors.<ref name="Turcotte Turley Johnson 2014">{{cite journal |last1=Turcotte |first1=Martin M. |last2=Turley |first2=Nash E. |last3=Johnson |first3=Marc T.
