Diversifying Selection Sometimes two or more distinct phenotypes can each have their advantages and be selected for by natural selection, while the intermediate phenotypes are, on average, less fit. Known as diversifying selection (see the figure below), this is seen in many populations of animals that have multiple male forms.

The solution, however, could be simpler than you would expect. In this article, we will show how to achieve true diversification through asset class selection, rather than stock picking and market In both genomes, diversifying selection on genes involved with DNA replication was surprisingly common given the fundamental conserved nature of the DNA replication process (Fig. 4).
