Movement, growth, and fertility defects in the fat-6;fat-7 double mutants. (A) Movement assayed by thrashing in liquid. (B) Time in hours for animals to reach the L4 stage. Nonsupplemented wild type are compared to fat-6;fat-7 double mutants grown without supplementation or supplementation with 18:1Δ9 or 20:5. (C) Average number of progeny produced per adult for wild type, fat-6, fat-7, and fat-6;fat-7 individuals. (D) Life span of wild type and fat-6;fat-7 at 20°. (E) Average progeny produced by individual adults over 2 days for wild-type and fat-6;fat-7 double mutants grown with control and 18:1Δ9 or 20:5 supplementation. All error bars represent the standard error.
