This track shows a measure of evolutionary conservation in seven species of the genus Saccharomyces based on a phylogenetic hidden Markov model (phastCons). The graphic display shows the alignment projected onto S. cerevisiae.
The genomes were downloaded from:
In full display mode, this track shows the overall conservation score across all species as well as pairwise alignments of each species with $Organism. The pairwise alignments are shown in dense display mode using a grayscale density gradient. The checkboxes in the track configuration section allow the exclusion of species from the pairwise display; however, this does not remove them from the conservation score display.
When zoomed-in to the base-display level, the track shows the base composition of each alignment. The numbers and symbols on the Gaps line indicate the lengths of gaps in the $Organism sequence at those alignment positions relative to the longest non-$Organism sequence.
