This type of deep sequencing lets researchers search for minor variants in a virus that can acquire mutations and ultimately take over. (scientificamerican.com)
Even later into the game, there are only a couple of minor variants of pre-encountered enemies. (coin-drop.com)
It takes several generations for selection to reduce frequencies of risk - associated alleles which will result in their overrepresentation among minor variants as we observe for E / LS independent diseases.» (sciencedaily.com)
