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 their brightly colored feet at their prospective partner. Frigatebirds are known for their unusual displays and breeding system. Unlike other seabirds, frigatebirds have a lek-breeding system where displaying males aggregate in groups of up to 30 individuals with prospecting females flying overhead. However, unlike classic leks, the pair then builds a nest on the male’s display site. The male then participates fully in nest defense, incubation, and chick-rearing. The main display that male frigatebirds use to attract females is a “gular presentation” where the male inflates his bright red throat pouch, points his head upwards and opens his wings. It
