Table 2. Number of events and mean TE mutation rates (per copy per generation, including 95% confidence intervals [CI]) for gains and losses based on whole genome sequence data from 66 Daphnia magna mutation accumulation and extant control lines descended from 9 starting genotypes collected from Finland, Germany, and Israel.
