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 Title: Re: In guinea pigs short fur (s) is dominant to long fur (s) and brown fur (B) is do Post by: bio_man on Mar 29, 2015 Emsheppard, did this solve your problem?
