Answer:
The saying 'each dog barks in his own yard' means that every organism is brave at his/her place or criteria. Outside the normal circumstances of that organism, the organism will not be able to perform.

Answer:
The correct option is<em> C) It makes the overall crop more susceptible to pests or disease.</em>
Explanation:
The reduction in genetic variation of a crop plant will cause serious threats to the particular crop population. If the genetic diversity will be low, then threats like a disease or a pest can invade the plant population as a result of which the entire population might become endangered.
Increased genetic variation ensures that some of the varieties might be able to adapt better to the changing threats as a result of which the whole of the population is at very low risk of getting erased.
