Comparison of long/both variant(s) normalized expression ratio of timeless in different populations from different light-dark cycles and temperatures. Comparison of long/both variant(s) normalized expression ratio of timeless in different populations from different light-dark cycles and temperatures. Conditions are given in the form: population, temperature (°C), and light dark cycle separated by an underscore. Populations are abbreviated as: Az = Azalea, Fa = Fairbanks, La = Lahti and Py = Pyhätunturi. Blue boxes indicates the LD of 22:2 and white boxes constant light (LL). Riikka Tapanainen et al.
