Pathways of a neutral networks

20 Sep 2022

Mutations must maintain a similar fitness level compared to the one before and after them if diversity is to increase. If the mutation negatively impacts the variant, then the pathway to reach other variants will not be accessible. The above image shows a short sequence and the mutations that come from it. As can be seen, either the mutations maintain the same fitness level as the one before them and go on to form new mutants, or they are of lower fitness level and die out. Please note that the sequence is just an example and does not specifically relate to this research. This image appears in the press release: Tracking a network of 100,000 mutants.
