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
The Different Forms of Flowers on Plants of the Same Species is thus a triple chance of the maximum of fertility...There is thus the clearest proof that these complex arrangements have the important end of securing both a more abundant and more vigorous offspring.” Observations and experiments still continue today to further the understanding of this phenomenon instigated by Darwin in this original and seminal work. The Different Forms of Flowers on Plants of the Same Species The Different Forms of Flowers on Plants of the Same Species is a book by Charles Darwin first published in 1877. It is the fifth of his six books devoted solely to the study
