Can anyone think of any reason why organisms rarely, if ever, have 2N chromosome numbers greater than 100?

There is no real answer to this question, however, it was observed that:
1. smaller number of chromosomes = larger chromosomes
2. large number of chromosomes = smaller chromosomes.

be advised that that is not by far always the case. Ophioglossum has 2n=1240 something..
