Mageveekäsna Ephydatia fluviatilis populatsiooni geneetiline analüüs
found in either ITS1 or ITS2 sequences for this specimen. Most of see Figure 1, two lower electropherograms, respectively) displayed
the ITS2 sequences obtained for this specimen were of such bad a distinct signal for A in addition to T. The same substitution also
quality, that they were unsuitable for precise analysis. However, appeared in one of the clones from the specimen R, whereas direct
visual examination of the chromatograms confirmed that in all of sequencing of the ITS1 region amplified from the same specimen
them the length variant of 323 nt was dominant, and the other showed the signal intensity caused by this substitution below the
ones, if present, were there in indistinguishable amounts or 10% threshold. Accordingly, this substitution was not considered
comparable to the noise level
