According to these articles, it is a quality that was bred: "Chinese archaeologists have claimed that pigs have been domesticated there for 7,000 years. This is from carbon-14 evidence dating pig bones at sites spread widely over the country. It is not only by their bones that prehistoric domesticants can be recognized but also artistic representations give clues. It was only after domestication that pigs gained curly tails or lop ears. In 3486 B.C., emperor Fo-Hi of China decreed that swine should be bred and raised." http://72.14.205.104/search?q=cache:BooEg-KA4B4J:www.angrin.tlri.gov.tw/apec2003/Chapter4TWPig.pdf+pigs+curly+tails+dominant&hl=en&ct=clnk&cd=15&gl=uss "The last physical part that’s different from a tame pig is the tail. A wild hog’s tail is usually straight and tufted at the tip. A domestic pig or a wild hog with Chinese genes has a curly tail." http://www.blackmouthcur.com/HA02.htm Only domestic pigs have the familiar curly tail; wild pigs have straight tails. http://www.sandiegozoo.org/animalbytes/t-wild_swine.html
