Causes of Variation

Interspecific - the variation that exists between different species. Eg. horses, vary from ducks.

Intraspecific - the differences that occr within a species. Eg. the length of a giraffes' neck.

Genetic Variation is inherited.

All members of a species have the same genes. Induviduals within the species have different versions of the gene - alleles.

The alleles make up the genotype.

Environmental Variation.

The phenotype (appearance) of an induvidual is affected by the environment.

Eg. plant growth, fur colour, accents.

Variation is often a combination of genetics and the environment.
