Breeding of strawberries variety "Old Black", which is of uncertain origin. This variety was created by pollination, not direct manipulation of the plant's genes. Molecular breeding is the application of molecular biology tools in a breeding program. Genetic engineering is typically defined as the introduction of non-native genes into an organism. An excellent example of transgenic modification is in the case of cold resistant strawberries. In one particular variety genes from the arctic flounder, a fish that lives in very cold water, were used to give plants resistance to cold. This modification works because of the genetics of the arctic flounder. It lives
Rearing (horse) more easily rear. If a horse manages to rear while under saddle, the rider has the best chance of bringing the horse back to the ground by leaning forward, keeping the reins slack and, in some cases, reaching around the neck of the horse to distribute as much weight as possible to the forehand. Once on the ground, the rider can prevent further rearing by asking the horse to move, either forward or in circles. Rearing can be caused by fear; a horse that sees something alarming in front of it may stop and, if asked to continue forward, may
