what are the factors that increase mutations? and what is transgenic and what are ads and dis of cloning???? help me

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.
