The term "biodiversity" literally indicates the diverse biological species within an ecosystem. Biodiversity, though, goes beyond simply a literal list of species; it also encompasses the interactions between the species, how they survive, what they do, and the living conditions in which they exist. Although it is easy to give a definition to the word "biodiversity," it is not quite so easy to explain exactly why we should be interested in and concerned about the biodiversity of an ecosystem. There are, though, specific benefits to biodiversity that affect every one of us on this planet.

Mosaicism or genetic mosaicism is a condition in multi-cellular organism in which a single organism possesses more than one genetic line as the result of genetic mutation. Genetic mosaics may often be confused with chimerism , in which two or more genotypes arise in one individual similarly to mosaicism. In chimerism, though, the two genotypes arise from the fusion of more than one fertilized zygote in the early stages of embryonic development, rather than from a mutation or chromosome loss. Genetic mosaicism can result from many different mechanisms including chromosome nondisjunction , anaphase lag , and endoreplication.
