What is metagenomics? What is metagenomics? the sequencing of only the most highly conserved genes in a lineage the sequencing of one or two representative genes from several species genomics as applied to a species that most typifies the average phenotype of its genus sequencing DNA from a group of species from the same ecosystem

The correct answer will be option-sequencing DNA from a group of species from the same ecosystem

Explanation:

Metagenomics is the molecular genetic tool used by the molecular biologists in studying the DNA samples of the uncultured organisms.

The metagenomics involves the collected samples of the environment directly sharing the same ecology. This involves the collection of samples of multiple organisms at the same time as the case of microorganism and then differentiating the DNA samples.

The technology provides an advantage over genomics and used by the environmentalist and microbiologist mostly.

Thus, the selected option is the correct answer.
