Benefits:

Selective breeding has shown to have benefits in certain cases where the methods have been used successfully. Benefits that have been demonstrated in these cases are:
- Health benefits for the organisms selectively bred (i.e sheep's tails lost in selective breeding, keeping them safer from bacteria being caught in the wool from faeces and endangering the sheep's health)
- An increase of quality product from animals (i.e Cows being selected for their milk, and therefore better quality milk is being produced)

Risks/ Concerns

Of course, the processes of selective breeding are not foolproof. Things can go wrong, sometimes just miniscule, other times much worse. Some examples of risks and concerns associated with selective breeding are:
- A lack of variety in plant species and therefore the species being at risk if there is an extreme change in conditions (i.e weather, drought, etc.)
- An increased risk of genetic disorders if selective breeding is continued for a prolonged period of time (i.e inbred depression, when an individual's fitness and fertility is reduced as a result of past generations experiencing inbreeding)
