  • 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.
