Increased survival in the selected populations post cold and heat shock. (A) Percent survival of two–three days old virgin flies of the FSB and FCB populations exposed to cold shock for 1 h as described in Methods. (B) Percent survival of two–three days old virgin flies of the FSB and FCB populations exposed to heat shock for 1h has described in Methods. The number of dead flies was counted 24 h after exposure. n = 300 male and female flies at a density of 100 males or females/cage were used for each replicate population of FSB and FCB. Data are represented as mean ± SEM. *p < 0.05, **p < 0.01.
