Fig. 3From: Rapid Increase in frequency of gene copy-number variants during experimental evolution in Caenorhabditis elegans Comparison of duplication and deletion spans in adaptive recovery versus spontaneous mutation accumulation (MA) lines. a The span of 24 independent duplication events in the adaptive recovery populations compared to the duplication span of 14 spontaneous duplications during MA [8]. The span of duplications during adaptive recovery is significantly larger than duplications detected under spontaneous MA conditions (p < 0.0001). b The span of 18 deletion events in the adaptive recovery populations compared to the deletion span of 11 spontaneous deletions during MA [8]. The deletion span for 18 deletion events in the adaptive recovery populations was significantly greater than the span of spontaneous deletions during MA (p = 0.032)Back to article page
