AquAdvantage salmon anadromous GM male salmon lack reproductive success and have a reduced number of surviving offspring. GM salmon's lack of fertilization success can be attributed to nest fidelity, quivering frequency, and spawn participation. Under simulated competition environments, 94% of siring occurred by wild-type salmon, while only 5.4% was attributed to GM salmon. This advantage allows more than twice as many wild-type offspring to be produced. Other characteristics that could cause wild-type males to be chosen more frequently could be the lack of growth of the kype, the hooked jaw of a male, and red coloration on anadromous males, which demonstrates sexual
March of the Penguins open water where the penguins can feed. However, by the end of winter, the breeding ground is over away from the nearest open water. To reach it, all the penguins of breeding age must traverse this great distance. The penguins practice serial monogamy within each breeding season. The female lays a single egg, and the co-operation of the parents is needed if the chick is to survive. After the female lays the egg, she transfers it to the feet of the waiting male with minimal exposure to the elements, as the intense cold could kill the developing embryo. The male
