Genetic diversity is a characteristic of ecosystems and gene pools that describes an attribute which is commonly held to be advantageous for survival -- that there are many different versions of otherwise similar organisms. For example, the Irish potato famine can be attributed in part to the fact that there were so few different genetic strains of potatoes in the country, making it easier for one virus to infect and kill much of the crop. In ecology, an ecosystem is a naturally occurring assemblage of organisms (plant, animal and other living organismsâalso referred to as a biotic community or biocoenosis) living together with their environment (or biotope), functioning as a unit of sorts. ...

Geneticdiversity is a characteristic of ecosystems and gene pools that describes an attribute which is commonly held to be advantageous for survival -- that there are many different versions of otherwise similar organisms.
For example, the Irish potato famine can be attributed in part to the fact that there were so few different genetic strains of potatoes in the country, making it easier for one virus to infect and kill much of the crop.
The neutral theory of evolution proposes that diversity is the result of the accumulation of neutral substitutions.
Geneticdiversity in a population means that the population contains most of the possible alleles (alternate sets of plans) for a particular gene locus rather evenly distributed throughout the population.
The "wholesale genetic slaughter" method may be appropriate in a geneticallydiverse population with only an occasional individual case of the disease in question.
A reasonable course of action in any genetic disease demands that attention be paid both to removing the gene where possible without seriously degrading the genetic viability of the population, and taking steps to provide increased geneticdiversity if it is needed.
