Variation 

Inhertiance vs. Environmental 

• Genes you inherit from your parents 
  

Eye colour, skin colour, freckles 

• Way you lead your life is environmental 
  

Scars, hair dye, length of hair

Measuring variation

Line graph

Bar graph

Dichotomous Keys (dividing into 2 parts)

Tool to identify different 
organisms by appearance
to discover their name

Steps are broken into couplets 

By following the key any person 
will be able to identify their specimen

Numbered key

Branched key

The classification system

Binomial system (means 'two names')

Second name = species

• Organisms that can reproduce together and produce fertile offspring

First name = genus

• organisms that are closely related but cannot reproduce together
