Phylogenetic reconstruction of ancestral character states for gene expression and mRNA splicing data
13 years 6 months ago
Background: As genomes evolve after speciation, gene content, coding sequence, gene expression, and splicing all diverge with time from ancestors with close relatives. A minimum e...
