I want to know the answer to the following question:
What accounts for the breakdown of the relation between genome size and morphological complexity in higher eukaryotes?
All the background I'm provided with is that "The genome size is positively correlated with the morphological complexity among prokaryotes and lower eukaryotes; however, after mollusks and all the other higher eukaryotes above, this correlation is no longer effective.". Is that enough to answer the question?
