Variation

Variation types
Dicontinuous

This type of variation has a limited number of values. EG: if a person can roll their tongue or not. It only has 2 vvalues, and someone cannot 'half roll' their tongue

continuous

This kind of variation has a range of values available. For example, height is a continuous variation because everyone is a different height. It is from this that we can calculate averages for certain types of people. EG: ages

The two causes of variation are
Influences by the environment

Traits that come from the environment.

EG: language spoken, length of hair

Both

Traits that come form both variation causes.

EG: height, colour of skin, weight

Genetic inheritance

Traits that come through the genes.

EG: eye colour, shape of nose

It is the differences between people
