WebIn this review, I give an overview of the study of GP maps with particular emphasis on these structural properties, and discuss a model that attempts to explain why these properties arise, as well as some of the fundamental ways in which the structure of GP maps can affect evolutionary outcomes. WebGenetic changes occur as a consequence, because the genotypic fitnesses may shift so that different sets of alleles are favoured. The opportunity for directional selection also arises when organisms colonize new environments where the conditions are different from those of their original habitat. shoe zone fraserburgh

Different types of natural selection can impact the distribution of phenotypes within a population. In (a) stabilizing selection, an average phenotype is favored.

A new hypothesis is that all Homo Sapiens originally had Dark Eyes (Brown) and that one individual about 6,000 to 10,000 years ago had a mutation which partially turned off the gene for Dark Eyes which reduced the amount of Melanin in the eyes. It is further believed that all people with blue eyes are descended from that individual. shoe zone flip flops ladies
