Which two statements indicate the societal benefits of practices based on genetic engineering?
the revival of the Alabama cotton industry by creating GM cotton to resist bollworms
the dependency of farmers on corporations for supply and price of GM seeds in the market

Farm animals are genetically modified to fulfill the increasing human demands for milk, eggs, meat, and other things. The insertion of human growth factors inside the genome of pigs is one such example of speeding up growth in pigs. The gene is inserted in the fertilized eggs and then inserted in female pigs to produce genetically modified offspring. Which option indicates the ethical challenge of the given process?
A. A greater number of people will start consuming meat.
B. Many of the embryos that undergo genetic modification do not survive.
C. The pigs that grow faster will outcompete other pigs for food resources.
D. There are more chances of the transfer of disease from animal to human.

.
A group of researchers developed genetically modified soybean seeds. These seeds are incorporated with a gene from Brazil nuts. These nuts are rich in essential amino acids that are not synthesized by the body and are present in very low amounts in ordinary soybeans. Based on the information, what is likely the disadvantage associated with consuming GMO soybeans?
They can change the taste of the soybean.
They can reduce the digestion rate of nuts.
They can reduce the nutritional value of the soybean.
They can cause allergic reactions in people with nut allergies.

Farmers perform genetic crosses between tomato plants having bigger fruits and tomato plants having the highest number of fruits. This resulted in the production of all tomato plants with a bigger and higher number of fruits. Based on the information, what could be the negative impact of the given process on plants?
It will reduce the genetic variation in plants.
It will give rise to fruits that are not suitable for consumption.
It will decrease the chances of the disease spreading in plants.
It will reduce the fertility of the soil in which these plants are grown.
