Answer:
Metagenome.
Explanation:
Metagenomics is the study of genetic material recovered directly from environmental samples. The broad field may also be referred to as environmental genomics, ecogenomics or community genomics.
A metagenome is DNA from a group of species. In metagenomics, a metagenome is collected from an environmental sample and sequenced. Again, computer software accomplishes the task of
sorting out the partial sequences and assembling them into specific genomes. The ability to sequence
the DNA of mixed populations eliminates the need to culture each species separately
