What we’re reading: The tiger genome, pooled sequencing for population genomics, and more fretting about academic careers

Cho YS et al. 2013. The tiger genome and comparative analysis with lion and snow leopard genomes. Nature Communications 4:2433. doi: 10.1038/ncomms3433.

Through comparative genetic analyses of these genomes, we find genetic signatures that may reflect molecular adaptations consistent with the big cats’ hypercarnivorous diet and muscle strength. We report a snow leopard-specific genetic determinant in EGLN1 (Met394Lys39), which is likely to be associated with adaptation to high altitude.

Next generation sequencing of pooled samples is an effective approach for studies of variability and differentiation in populations. In this paper we provide a comprehensive set of estimators of the most common statistics in population genetics based on the frequency spectrum, namely the Watterson estimator θW , nucleotide pairwise diversity Π, Tajima’s D, Fu and Li’s D and F , Fay and Wu’s H, McDonald-Kreitman and HKA tests and Fst, corrected for sequencing errors and ascertainment bias.
