Advantages:
Cuttings and tissue cultures allow you to get the best plants (the ones with the best traits e.g fruit produced)
Tissue cultures can be created from a few tiny cells
Disadvantages:
No variation - less likely to survive if introduced to something new e.g. pest
Tissue culture can be expensive in some instances

Advantages:
Cloning animals via embryo cloning means we can get extra produce e.g. more meat from cows
Cloning animals means we can get beloved prized pets back in some form after death (a couple from the US actually did this for over 100,000 dollars)
Adult cell cloning is good as we can get a new animal from grown cells e.g. a skin cell of a good sheep
Disadvantages:
Adult cell cloning and embryo cloning has a low success rate
Both methods can be very expensive
Embryo destruction - animal activists may not like this (immoral/ethical argument)
