Cloning the dog breed will get an exact copy of it’s genetic material from the donor itself. Hence whatever heredity defects that the donor has or mutations it has inherited will be the same for the clone cell. E.g. cancer cells –> if donor has a susceptible risk of getting cancer, the clone would also inherit it.

One advantage is that genetically modified corn is less susceptible to disease and pesticides. Another advantage is the prevention of famine which solves the immediate problem. One disadvantage is it could damage your current crops as is could alter the ecosystem. Another disadvantage is makes you in debt to the other nation.
