rDNA, ribosomal DNA.
↵a Indicates the sequences that are obviously low in abundance.
↵b Likely cross-hybridization among 359 bp, 372 bp, 260 bp, and other related repeats.
↵c Without rDNA.
↵d Roy et al. (2005) reports the presence of rDNA (using Py12 and 240 bp probes) on D. sechellia Y, although much weaker than X rDNA. This may be because our IGS-240 probe does not cover the entire length of the 240 bp sequence, and our probe sequence does not hybridize well to D. sechellia IGS.
↵e Yadlapalli and Yamashita (2013) described its presence on Y but this chromosome spread did not find dodeca on Y, possibly due to differences in hybridization conditions or strain.
