Moderate nucleotide diversity in the Atlantic herring is associated with a low mutation rate Open
The Atlantic herring is one of the most abundant vertebrates on earth but its nucleotide diversity is moderate (π = 0.3%), only three-fold higher than in human. Here, we present a pedigree-based estimation of the mutation rate in this spec…
