1/2
If you do a Punnett square for fur color, all of the offspring will be heterozygous possessing brown fur so the probability of fur color is: 1
If you do a Punnett square for fur length, one half of the offspring will have long fur so the probability is: 1/2
By multiplying the probabilities of the two traits you get: 1 * 1/2 = 1/2
