If humans have 2,900 mb, a specific member of the lily family has 120,000 mb, and a yeast has ~13 mb, why can't this data allow us to order their evolutionary significance?
a) size matters less than gene density. b) size does not compare to gene density. c) size does not vary with gene complexity. d) size is mostly due to "junk" dna. e) size is comparable only within phyla.

The correct answer will be option-C

Explanation:

The genome size is the total amount of DNA present in the organisms which includes both coding and non-coding sequences. The genome size is measured in the C-value.

The gene complexity is the complexity in the DNA of an organism which arises due to gene duplication and other mechanisms.

The gene complexity does not show correlation with the size of the organisms which is expected that the larger eukaryotes will have a larger genome size. This is known as the C-value Paradox.

In the given question, since the yeast contains 13 MB, Humans contains only 2,900 Mb whereas a plant of Lily family contains about 120,000 Mb which shows that the lily should be the largest eukaryote which is not the case.

Thus, Option-C is the correct answer.

covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds.
