Table 2

Rates of loss per ancestral insertion per generation (with standard errors) for six families of DNA transposons across mutation-accumulation lineages where sex was promoted (sexuals) and prohibited (asexuals). Number of high-loss loci (loci where losses were observed in more than three lineages) and t-test results are shown.
