Question : C-value is the characteristic DNA content in a haploid cell of a given species. Earlier it wasconsidered 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 the organisms . For example, the cells of some salamanders may contain 40 times more DNA than those of humans. Which of the following explains thisC-value paradox?

Answer»

Polyploidy
Chromosomal mutation
