According to plant-genetics experts, the benefits of using genetically modified crops primarily include disease and pest resistance, an improved ability to weather environmental stresses, and improved product quality (Smith and Parr, 2005, p. 700). However, some drawbacks are possible for such plant variety. These include impact on non-target species, exchange of genetic material between the transgenic crop and related plant species, and selection for resistance among populations of the target pest (Smith and Parr, 2005, p. 700). 6.

A farmer planted a field of Bt 123 corn and wants to estimate the yield in terms of bushels per acre. He counts 22 ears in 1/1000 of an acre. He determines that each ear has about 700 kernels on average. He also knows that a bushel contains about 90 000 kernels on average. What is the farmers estimate of yield in
