(ii) Genetic research helps to increase the yields in a short time.
Disadvantages of genetic research:
(i) Unethical genetic modification such as making biological weapons that can harm humans.
(ii) Genetic research that produces new species will cause the original species to become extinct
What problems will arise if ethics and values are not practised in genetic research?
