Explain how combinatorial gene regulation permits regulation of a large diversity of genes with relatively few regulatory proteins
What will be an ideal response?
Although the number of different regulatory proteins is limited, in combination they can interact with a far greater number of genes with specificity.

The Janzen-Connell hypothesis:
A. proposes that interactions with hostspecific pathogens, herbivores or seed predators play a role in decreasing plant diversity. B. was based on the observation that seeds often suffer lower rates of herbivory when growing directly beneath a parent tree. C. was supported by research that demonstrated that seeds that disperse far from their parent tree will escape from seed predators. D. was supported by data that indicated that seed and seedling mortality was not density dependent, thus favoring more common species. E. indicates that rare plants do not survive well in the tropics.
