Definition: Heterochromatic regions of the chromosome found at silenced mating-type loci.

View Ontology: (graph) | (text)

This table lists the methods used to annotate genes either directly to the term mating-type region heterochromatin (1 gene) or to its variants containing one or more qualifiers (1 gene). Note that some genes may have been annotated by more than one method so the numbers in the table below may not add up to the totals given here.
