Which of the following is most likely to be the direct result of lack of genetic diversity in a food crop such as corn?(A) Decreased kernel size- kernel size does not affect the corn’s ability to reproduce and grow.(B) Decreased potential yield- the potential yield of corn does not helpcause the corn to become extinct.(C) Decreased dependence on chemical fertilizers- because a decreased dependency on chemical fertilizers would make the corn stronger, and a lack of genetic diversity makes it weaker.(D) Increased susceptibility to plant disease- if corn is more susceptible to plant diseases, then it will be at a risk of extinction.(E) Increased resistance to pests- would make the corn stronger, and a lack of genetic diversity makes it weaker.

Genetic variation helps a population to develop despite varying environmental conditions as to decrease the risk of extinction. Genetic diversity is used to create improved crop varieties with traits such as yield, pest resistance and environment stress. Lack of genetic diversity in corn will make it susceptible to plant diseases and be at risk of extinction.

The option that is most likely to be the direct result of lack of genetic diversity in a food crop such as corn is that increased susceptibility to plant disease when corn is more susceptible to plant diseases, then it will be at risk of extinction.

Genetic diversity simply means the variation which occurs in the genetic composition among the individuals in a particular population.

It should be noted that the diversity in the genetic level is vital in showing the similarities in a gene and the differences.

In this case, if corn is more susceptible to plant diseases, then it will bring about a situation where there is a reduction in corn and then it will be at risk of extinction.

In conclusion, the correct option is D.
