Abundance orA repeats was similar to C repeats. AC was a little more than two times as abundant much as AG. However, AT and CG repeats were rare. For tri- and tetramer repeats, AGC,AAAC and AAAT predominated while ACG, ACT, AGG, CCG, ATGC, CCCG, ACTG, AACT, ACGT, AGAT, CCGG,ACCT and AGCT were rare. For some pentamer repeats, one was completely absent on a certain chromosome, even on several chromosomes.
