Answer:
Mutation is the source for new genetic variation: Genetic variation is brought about by random mutation. Without mutation, genetic variation cannot occur. Mutation is a change in the genetic code in DNA and can lead to a change in the protein that is coded for that segment of DNA.
Explanation:
Mutations are changes to an organism's DNA and are an important driver of diversity in populations. Species evolve because of the accumulation of mutations that occur over time. ... This mutation has introduce a new allele into the population that increases genetic variation and may be passed on to the next generation.

Animals can be engineered to require less food, grow quicker, and leave behind less evironmentally damaging waste.
-Animals can be engineered to be more resistant to harmful and painful diseases.
-Animals can be engineered to produce more omega-3 fatty acids, to provide leaner meat, and to make more milk.
-Animals can be engineered so their tissues, organs, and cells can be transplanted into humans.
-Animals can be engineered to produce certain substances that offer a new source of medicine.
-Animals can be engineered to reproduce much faster.
negative impacts.
It is unethical.
-Some food companies have refused to use meat or milk that is from genetically engineered animals.
-Some consumers are complaining that the animal drug rules do not regulate genetically modified animals properly.
-This process is potentially dangerous and can be very harmful.
-When engineering animals the natural ecosystem can be disturbed.
-Some animals die in experiments while other are born deformed or huge.
-Animals may live in odd comditions that are affect their natural way of life.
-Most injected eggs do not end up creating a living animal.
