How might genetically modified crops affect biodiversity

Since genetically modified crops (a.k.a. GMOs) reinforce genetic homogeneity and promote large scale monocultures, they contribute to the decline in biodiversity and increase vulnerability of crops to climate change, pests and diseases. The Impact of GMOs on Biodiversity Genetically modified crops grow in a dynamic environment and interact with other species of the agro-ecosystem and surrounding environment.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
