Is the number of possible QTL for asymmetry phenotypes dependent on thermal stress?
In bilateral organisms, fluctuating asymmetry (FA) was often used as an index of developmental instability but FA was not always found to be higher in stressful environments. An intercontinental set of recombinant inbred lines (RIL) was used to search for genetic variation in fluctuating asymmetry (...
