| Title | Testing for evidence of inefficient selection in bdelloid rotifers: do sample size and habitat differences matter? |
| Abstract | Preliminary evidence on inefficient selection has indicated that asexual (=parthenogenetic) animals suffer from a greater accumulation of deleterious mutations compared with their closest sexual sister taxa. However, previous work on bdelloid rotifers did not completely rule out the confounding effects of sample size and habitat differences. Here, we present further evidence of inefficient selection against deleterious mutations in the bdelloid rotifers in comparison with their closest clade, the monogononts, by taking account of larger samples. However, the analysis of samples from both clades co-occurring in the same location seems to contradict the hypothesis. Both groups show evidence of the accumulation of deleterious mutations in mitochondrial DNA, but further population sampling and inclusion of additional genes is needed to resolve this issue. |
