Learning Mitigate Genetic Drift – Scientific Reports

Genetic drift describes the random fluctuations in allelic diversity in a population. In this paper, we estimated that a systematic increase in organisms’ chances of survival in response to a random source of mortality, e.g., learning from experience, attenuates genetic drift (decreasing number of alleles) even when overall death rates remain the same. same. To …

Strength of SARS-CoV-2 genetic drift across time and spatial scales in England

In a recent study published on bioRxiv* preprint server, researchers developed and validated an approach for the joint inference of measurement noise and genetic drift by analyzing lineage frequency time series data.
