WebSep 24, 2015 · The answer to your headline question is that no, fixation rate is not always equal to the mutation rate for neutral alleles. For instance: Fixation rates for neutral alleles are affected by changes in population size, given a constant mutation rate. In general, fixation rates are lower in growing populations ( Waxman 2012 ). WebApr 13, 2024 · To simulate a clinical scenario of autograft fixation under low mechanical load, we presented the first in vivo model: a rat fibula glued to the tibia, on which the TTCP/OPS-nPDA adhesive (n = 7) was shown to be effective in stabilizing the graft without displacement (a clinical success rate of 86% and 71% at 5 and 12 weeks, respectively ...
