The relative importance of genetic drift and natural selection on flower colour in the annual desert plant Linanthus parryae‚ whose dominant blue and recessive white phenotypes are controlled mostly by one gene‚ is debated. Epling and Dobzhansky found that spatial distribution of blue- and white-flowering plants was consistent with genetic drift‚ and Wright found that spatial distribution was consistent with that expected in isolation by distance‚ both supporting the predominant importance of genetic

Energy Source of Natural Hazards Disasters occur where and when the earth’s natural processes concentrate energy and then release it‚ killing and causing destruction. Four energy sources make the earth an active body: 1) the Earth’s internal energy; 2) solar energy; 3)gravity; 4)the impact of extraterrestrial bodies The interior of the Earth holds a tremendous store of heat released primarily from the ongoing decay of radioactive elements. Earth’s internal energy flows unceasingly toward the
