When fruit flies get sick, their offspring become more diverse

When fruit flies get sick, their offspring become more diverse due to increased genetic variability. This adaptation may help the offspring survive future threats from the same pathogens. The findings demonstrate that parents can alter the genotypes of their offspring, a strategy that could be beneficial for survival.
