Effects of CYB2 expression on brood sizes and lifespans. (A) Wild-type (N2) and mutant (LB25 and LB27) animals were allowed to lay eggs at 20°C, and all progeny were counted. The values reported are averages of at least 18 counted broods. (B) Transgenic animals cultured at 20°C were monitored daily and scored as dead when they no longer responded to gentle prodding. The values reported are averages of a minimum of 24 animals. Black bars, no CYB2 transgene; white bars, Pnuo-1::CYB2-containing transgenes; gray bars, Plet-858::CYB2-containing transgenes. All P values (*, P < 0.05; **, P < 0.01) are derived from a two-sample t test when comparing with the corresponding strain without CYB2.
