The sum of different
genotypic or
phenotypic
characters within a given taxa or population. |

- Variability of
genotypes
(Genetic
diversity) The differences in the
genetic make
up among
populations of a single
species
and among
individuals within a population.
- Variability (heterozygosity):
Absence of uniformity, usually referring to lack of
genetic uniformity in a population.
- Variability among
living organisms (biodiversity):
the variability among living organisms from all sources
including, among other things, terrestrial, marine and other
aquatic ecosystems and the ecological complexes of which they
are a part; this includes diversity within species (Genetic
diversity), between species (Species
diversity) and of ecosystems (Ecosystem diversity)
- Variability (aberrance):
Manifest diversity or difference, divergence to true type
- Variability of population
(The proportion or ratio of organisms within a
community)
Instead of counting each and every
organism,
scientists measure the variability of populations to look for
change over time. For example in a given population the
variability may be 4 females for every 3 male.

|
|
The tendency to vary or
fluctuate around an average or expected value, or around a specific
average pattern. |

|
|
|
The statistical measure of variability
(variance) is a measure of the dispersion of a set of values
about its mean. |
