I have heard of big genomes in bacteria or plants where the plant itself hasn't a preceiveable ability for the genetic material as we understand it.

But what about,, genomes in general that have many abilities? what about small genomes with maybe uncommon high amounts of abilities?

And lastly, how would this sort of study be applied to evolutionary science where metrics/data can predict how evolution might spur suddenly or even where it is headed?
