For (b): Yet the DNA content of most C-positive regions in Phasmatodea is not clear. Thus, in the future, it would be very useful to estimate the DNA homology of telomeric C-bands in different Phasmatodea species. This task could be solved by chromosome microdissection of telomeric C-bands of one species followed by generation and labeling of a DNA probe by degenerate oligonucleotide-primed polymerase chain reaction (DOP-PCR) or whole-genome amplification (WGA) techniques. Other approaches using low copy repeats as probes  or high-throughput approaches are also helpful in this context . The telomeric C-bands in P. khaoyaiensis chromosomes are the most promising regions for the suggested microdissection approach. They are large and present in many chromosomes and there are chromosomes with telomeric C-bands in the short or long arms, and in both. It will also be possible to compare the DNA content in such C-bands and in pericentric C-bands, and among the different chromosomes.
