Theres two types:

Genetic Variation:

  • Characteristics determind by the inherited genes of parents.
  • Combining genes from two parents causes genetic variation.
  • Characteristic caused just by inherited:
  • eye colour
  • blood group
  • inherited disorders

Enviromental Variation:

  • The conditions that an organism live or grow in also causes differences between members of the same species.
  • For example maximum height of a plant could grow determined by its genes but whether it has enough room to actually grow depends on its enviroment.

Mutations include variation:

  • Mutations can result in a new phenotype.
  • The enviroment will change and the individual will either be better or less suited to the change.
  • These characteristics can spread through a spieces reletively quickly by natural selection.

Evolution:

Theory: All of todays spieces have evolved form…
