Columns: CH, chromosome; n, total interval; n1, the number of observations of 1; n2, the number of observations of 0; r, the total number of runs. *We calculated the average density of TEs and HighA satellites per 500 kb for each chromosome and then compared the observed density in each 500 kb interval across the chromosome to this average. If the observed density/average density is >1, this interval was considered to be putative heterochromatin and was denoted as 1. If the observed density/average density is ≤1, this interval was considered to be euchromatin and was denoted as 0. ^†P < 0.05.
