From: The fester locus in Botryllus schlosseri experiences selection

Locations of the codons with greater than 95% probability of ω greater than 1 across the fester locus. The numbers at the top of the figure refer to the exons sequenced. The analysis was done on four separate data sets - A-type East Coast alleles, A-type West Coast alleles, B1-type East Coast alleles and C-type East Coast alleles.
