factors tht increase mutations : mutagens such as ionising radiation- UV, gamma
transgenic : when an organism contain a gene from another organis usually to produce a particular protein
adv and disadv of cloning -
adv- produce gentically identical offspring .
no varairion.
can produce anytime of the year and is fast
more offspring

disadv- no varaiation and so doesnt lead to evolution.
