Nematode strain characterization. Average worm length (A), diameter (B) and body mass (C) were determined for the wild-type strain (N2), the mtl1 knockout strain (mtl-1) and the two snail MT knock-in strains carrying the full 10md-MT (10md-MT) and the 2d-MT construct (2d-MT) of Alinda biplicata under 0 µM Cd²⁺ conditions. Statistical analysis was performed on 15 worms per strain. Error bars represent the standard deviation at 95% confidence. Gray bars denote non-significant (ns) differences, or close-to-significant differences (p < 0.08) where a p value is given. A p-value close to significance (added in the figure above respective bars) indicates a biological trend. Significance is marked by asterisks.
