ing for the growth of a population. Most genetic traits of large populations are either positive or neutral; the original founder’s providing distinct traits that did not inhibit future growth. Neutral traits do not benefit or inhibit, such traits include eye color, fingerprint patterns, and facial shape. In Europeans, fingerprint loops are more common than whirls, while in Australian aborigines whirls are more common than loops. An example of a positive trait would be a resistance against malaria. Certain populations of the world each have their own unique genetic trait that changes the composition of their hemoglobin. In Africa it is Hb s, in Southeast Asia it is Hb E. Each of these traits are recessive and when homozygous recessive have harmful effects upon the person, when heterozygous they provide resistance to malaria. Because malaria is such a harmful disease in those areas, the people that it saves from malaria is usually higher than the number that die from having homozygous recessive genes for that trait....
