Answer:
He is either not carrying the gene for RP or the RP gene has mutated.
Explanation:
RP or Retina Pigmentosa is an eye defect inherited by a person from a parent. The disease is degenerative as the individual gradually loses his sight. It normally starts off as night-blindness and could go as bad as a total loss of sight.
The mutation of both the RPGR and RP2 genes which are responsible for the function and structure of light-reception in the eye accounts for most cases of Retina Pigmentosa disease.
Farmers should discontinue the use of Bt corn (genetically modified maize)as their negative affects on the health of the consumers have not been fully over ruled by the recent research. In my opinion, genetically modified crops, although, are resistant to various pests, should not be encouraged because of the toxic chemical contents used during their production. There's a strong likelihood of these toxic chemicals entering our food chain and also being harmful to other naturally growing plants, hence there's a need for more research before this idea is pursued.

The answer is D. learned behavior.
A change in behavior of an organism takes place due an experience is called learning. Animals learn behavior in many ways. On such way is given the question that anole lizard ate bright red butterfly instead small insects which are its normal food and became ill. Anole lizard learned through experience that bright red insects are not its food. Thus, a learned behavior is one that an organism develops by encountering experience.
