Rabbits of same species may have different genotypes and phenotypes which can be evident with the traits that is present. First, check if that particular species only has two fur colors. If so, we can say that one of the two fur colors may be the dominant trait and the other one may be the recessive. But one thing for sure is that the genetic code/s that affects the colors of the fur of the rabbits is different. Having a different genetic code means that there are different DNA sequences for the particular trait.
