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
Seabird breeding behavior Seabird breeding behavior The term seabird is used for many families of birds in several orders that spend the majority of their lives at sea. Seabirds make up some, if not all, of the families in the following orders: Procellariiformes, Sphenisciformes, Pelecaniformes, and Charadriiformes. Many seabirds remain at sea for several consecutive years at a time, without ever seeing land. Breeding is the central purpose for seabirds to visit land. The breeding period (courtship, copulation, and chick-rearing) is usually extremely protracted in many seabirds and may last over a year in some of the larger albatrosses; this is in stark
