Table 1 Average number of paracopies with the uncorrected sample standard deviation (SN) in precursors with multiple-copy peptides. Only full-length precursor sequences are considered; data without SN refer to a single complete precursor sequence. For hexapod orders lacking full-length precursor sequences, the maximum number in a partial sequence is given in parentheses. Note, that Collembola show the lowest number of paracopies by far
