Genetic Variation

Genetic Variation is caused by two main factors:

1) Competition
2) Environment-nutrition, selective pressures, predators

Members of the same species show variety (such as height, weight, hair/eye colour). Variation between different species is used to classify different organisms.

An allele is a version of a gene.

We share alleles with other members of other species and we share DNA sequences with other organisms, but not in the same order.

It is the combination of alleles which we inherit that makes us unique.
