Diversity governs the universe of rigid material to living organisms, from the observed phenomena to the complex thought processes, of the ideas into concrete products manufacturer. The contrast and diversity is the hallmark of all you can think of and the existence of life itself is characterized by genetic diversity. Billions of species populate the earth and each represents a manifestation of cosmic plan and coordinate the emergence and growth of all forms of life through the electoral pressure of evolution. And that what distinguishes the multiplicity of species is the uniqueness of every individual of any kind has its own features, all humans are different in both physical and mental characteristics Valoaan blue, and brown hair, skin and blond, and short stature, are all expressions of the superficial variety hereditary USA. And the same thing for the behavioral traits such as learning, memory and mood Pacific or bad.Was the first systematic study conducted for these variations on the fruit fly, not on human reproduction rate of this insect rapidly so that the hereditary changes quickly and seem to have all the fruit flies are similar. But it is not, it discloses, like all living species for a broad spectrum of phenotypic characteristics.Which determines the difference between species is that we as human beings may have been particles Dnna DNA molecules longer than animals and plants, the genetic length of the growing crew of the bacteria is 4.7 million pairs of rules, and yeast 15 million, 155 million fruit flies, and 3000 million human beings. That there are many exceptions to this rule; Vllkther from lower species DNA molecules longer than the DNA molecules rights; Vdzee mouse DNA, such as humans, and maize 5000 million, while the iris flower 9000 million. These exceptions are contradictory and do not link directly associated with the complexity of the organism. And phenotypic variation caused by genetic variation.These differences between the DNA molecules are distributed randomly along the molecule may be caused by mutations "Replace Newtadh another" or delete Newtadh or more. These variations, which can be likened to a series of markers along the DNA, called "Genetic markers".
