  • Entries are the number of mutation accumulation lines (out of a possible 29) that show significantly different mortality rates throughout life for each sex and whether the difference was toward increased or decreased mortality. Significance (P ≤ 0.05) was determined by least-squares regression of log mortality rate on age with time as a nonlinear covariate (see text). Numbers in parentheses indicate the number of lines that also show significant differences at specific ages (see Figure 3).
