Subfunctionalization: How often does it occur? How long does it take?
... In order to determine the relevance of subfunctionalization as an explanation of gene duplication, we need to understand what the model predicts. Lynch and Force (2000), see also Lynch et al. (2001), investigated the probability of subfunctionalization and the time until the outcome is determined in ...
