Despite speculation to the contrary, the population variation in the allele frequency is more likely due to neutral evolutionary processes than natural selection.

This model is able to predict 61% of population variation.

It is notable for the population variations each year as seasonal workers come to work on the extensive cotton fields.

The result is that C. odorata as now constituted is a species showing a high degree of population variation.

Among the population variations, three subspecies are recognized.

Studies have shown a variety of effects including timing changes in migration, breeding as well as population variations.

A prerequisite for heritability analyses is that there is some population variation to account for.

The population variation of the lynx and the hare is an example of a predator-prey cycle.

Environmental factors such as weather and forest plant growth that may affect this population variation have been studied.

The widespread distribution with population variations has led to nearly thirty subspecies being described.
