Solution
Paradox of C-values:
In the genome, the total amount of DNA is expressed in base pairs.
The so-called C-Value Paradox describes how genome size does not rise in lockstep with the perceived complexity of species, such as vertebrate versus invertebrate creatures, or "lower" against "higher" vertebrate animals (red box).
This is known as the C-value conundrum, and the C-value refers to the quantity of DNA present in a haploid cell. This is due to junk DNA, which is a section of DNA that has no purpose other than to store information (still debatable)
For a given species,
The amount of DNA in each cell of the body is constant.
The list of organisms on our planet, numbering in the millions, each has its own genome, the size of which varies from species to species, and no different species have the same amount of genome, genomic value, or character.
Within a phylum, order, or genus, the variation in genomic content (both quantitatively and qualitatively) is remarkably large, ranging from 105 to 1012 base pairs.
Animals have a 3,300-fold variety range, and land plants have a 1,000-fold variation range.
