Mapping between Ancestral centromeres and centromeres in extant species.

The first column lists the Ancestral centromeres, and the numbers in the subsequent columns lists chromosome numbers (or scaffold numbers for unfinished genomes) where the orthologous centromeres are found in the other species. Post-WGD species have up to two centromeres for each ancestral centromere. The final row lists the total number of chromosomes in each species.X, Centromere lost.+/−, Sense/anti-sense strand in S. cerevisiae.*, Orientation change.?, Possible orientation change (see text).r, Reciprocal translocation at centromere.i, inversion at centromere.
