Wild-type flies are more fecund and live longer than mutant flies. (A) Female fecundity (eclosing adults per reproductive female) in Hsp83 mutant (Hsp83P/P) and wild-type (Hsp83+/+) isofemale lines. Each genotype is represented by five isofemale lines labeled one through five. Data for each isofemale line are derived from three replicate matings of five males and five females. Error bars above each column indicate one standard error of the mean derived from the three replicate matings. (B) Cumulative survival rate of male and females in Hsp83 mutant (Hsp83P/P) and wild-type (Hsp83+/+) isofemale lines. The horizontal axis shows the number of days after eclosion, the vertical axis the fraction of surviving individuals after a given number of days (i.e., the cumulative incidence of survival). Red and blue data were obtained from five isofemale lines of Hsp83P/Pmutants and Hsp83+/+ wild-type genotypes, respectively.
