There are so few wolves that they have lost genetic variability.

Since their numbers are low there is a high risk of them losing too much genetic variability to survive.

Together they form a monophyletic group, with very low genetic variability.

In small populations where genetic variability is low, individuals are more genetically similar.

The world's plantations of cocoa are short on genetic variability.

There are many sources of genetic variability in a population:

Because of high genetic variability, seeds may have different characteristics compared to the parent plant.

In this area, the greatest genetic variability in the world was found.

The lack of genetic variability created a susceptible host population for the organism.

This comparison of genetic variability within (and between) populations is used in population genetics.

As for the dog's huge variety, "Genetic variability is built into a species so it can adapt if conditions change," he said.

If a population has no genetic variability, scientists say, it cannot evolve through natural selection in response to long-term environmental changes.

Micro-organisms, with their huge populations, also carry a great deal of genetic variability.

The species has a relatively high genetic variability for an uncommon island endemic.

The same study also showed the populations in Chile are relatively homogeneous with low genetic variability.

This family of enzymes has recently been shown to have a high rate of genetic variability.

Somaclonal variation leads to the creation of additional genetic variability.

Although the population has rebounded, its genetic variability is much less than that of the Southern elephant seal.

Its main export was genetic variability for large domestic animals too inbred in other populations.

The old land races can be considered as populations of genes and genetic variability is absolutely essential for further improvement.

Conservation activities include genetic analysis in an effort to understand the genetic variability of populations.

Because of this, a mutation breeding programme was initiated to generate new genetic variability.

Pre-adaptation may occur because a natural population carries a huge quantity of genetic variability.

Their reproductive success should shed light on the important issue of genetic variability in small, isolated populations."

In other words being a hermaphrodite would increase genetic variability and thus be considered advantageous to the organism.
