C-value is the characteristic DNA content in a haploid cell of a given species. Earlier it was considered that C-value correlates with organism complexity. However, it is now evident that C-value varies enormously among species and this bears no correlation with the complexity of hte organisms . For example, the cells of some salamanders may contain 40 times more DNA than those of humans. Which of the following explains this C-value paradox?

A

Polyploidy

B

Chromosomal mutation

C

Non-coding DNA

D

Coding DNA
