Most of our crops (corn, soy etc) are plants with extremely low genetic variation. Why do we plant crops with low genetic variation? What are the risks of this? From an evolutionary perspective, how can a lack of genetic variation harm crops?

Expert Solution

Corn crops are cultivated around the year due to their high demand and frequent of use of same variety of seeds and this continuous cultivation of these crops without any other rotational crops low genetic diversity is seen which are affected by the seasonal changes and soil fertility. Low genetic variance crops are used to increase the production within less time.

Use of low genetic variation crops pose a risk of damaged of crops of by a genetic disorder or climatic changes if the crops with high genetic variation the cops will be more disease and drought resistant. Plants with less genetic variance are susceptible to disease condition and my cause extinct of entire crop and this extinction may lead to removal of entire species of plant from land.

The crop seed market for commercially produced plants such as corn, cotton, soybean, canola etc. used to be close to perfectly competitive before 90s. As will be explained in the next question this market got less and less competitive since then. For the purpose of this question, consider a seed producer in Washington State in 1985 selling corn seeds. Suppose this company is making economic losses. a. How does the price of corn seeds compare to the average total cost...

The neutral mutation hypothesis does NOT suggest that: (a) The evolution of most genetic variation in a population is influenced by genetic drift (b) When natural selection is at work on protein variants, it will lead to little variation in the population (c) Most molecular variation is adaptively neutral- for example, most protein variants are functionally equivalent. (d) Natural selection is still an important evolutionary force (e) Genetic variation in a population is maintained mainly by natural selection
