摘要: We have started to test the effects of environmental extremes on expression genetic variation for traits likely be under selection in natural populations. shown that field heritability may high stress response contrast morphological traits, which tend show lower levels heritable nature compared with laboratory. Selection increased resistance can lead a number other evolutionary changes, and these underlie trade-offs between favourable stressful environments. Temperature marked influence life history traits. Heritabilities fecundity when parental flies are reared at low temperatures conditions. The development time is somewhat more complex temperature considered. Populations species margins ideal studying evolution.
