variations

Variation

• variation just means differences between organisms
• a human, cow, dandelion and a tree all look totaly different. thease differenes between species occur because there genes are totally different
• you also can see variation within species i.e. plants and animals which have basically the same genes will also show differences between them e.g. skin colour, height, flower size ect.

continuous + discontinuous

• continuous variation
• for exmple of these are things like height, wheight, skin colour, intelligence, leaf area ect. where the featuures can have any value at all
• discontinuous variation
• examples of these are things like eye colour or blood group where there are just a few distinct options, not a continuous range
