Final answer:
Multiple genes involved in plant immune responses increase specificity and efficiency, leading to robust disease resistance which is key for sustainable agriculture and crop diversity.
Step-by-step explanation:
The advantages of multiple genes working collaboratively to produce one immune response in plants include increased specificity and efficiency. This complexity allows plants to have a finely tuned immune response that can target a wide variety of pathogens, thanks to the vast array of antibody molecules that can be manufactured. Unlike having a separate gene for each antibody, this system relies on the genetic recombination and variable gene expression to create a diverse immune response. As a result, plants are better equipped to respond to and resist diverse pathogens, leading to improved disease resistance and potentially contributing to the improvement of agricultural yields and crop diversity. Therefore, the correct answer to the student's question would be A) Increased specificity and efficiency.Genomic tools in agriculture like genomics can be used to generate new hybrid strains with improved disease resistance, improved yield, and increased resistance to environmental stresses. Furthermore, maintaining biodiversity through genetic diversity allows for ongoing adaptation and resilience against evolving pests, contributing to the sustainability of agriculture.
