In cats, a temperature-sensitive allele produces the Siamese phenotype, in which the cooler extremities are dark and the warmertrunk area is lighter. A Siamese cat that spends most of its timeoutside was accidentally injured in a trap and required severalstitches in its right front paw. The veterinarian had to shave the furfrom the paw and leg, which originally had rather dark fur. Later,when the fur grew back, it was much lighter than the fur on theother three legs. Do you think this injury occurred in the hot summer or cold winter? Explain your answer
