Answer :
Answer:
a.
Explanation:
Based on the information provided within the question it can be said that the bananas had a lack of genetic variation. Genetic Variation refers to the difference in DNA sequences, without genetic variation a population or species cannot evolve in response to changes or other variables that place it at risk and may cause it to become extinct. Which is what happened with the bananas, since they lacked genetic variation they were not able to adapt to the fungus and it nearly wiped it out.
