B & D
The seasonal moult- and thereby colour change- of individuals is triggered by photoperiod (B) but natural selection determines the prevalence of colour-changing individuals in the population (D).
Northern colour-changing weasels continue to grow white coats (become ermine) in the winter even when transplanted south and animals from the southern population remain brown throughout the year even when moved to northern lattitudes.
