Answer:
On the basis of the given information, the dominant allele must be for black fur and the recessive allele must be for white fur.
Step-by-step explanation:
A variation of a gene, which will generate a certain phenotype, even in the existence of other alleles is known as a dominant allele. On the other hand, a version of a gene that needs to be homozygous when inherited in order to be articulated in the phenotype is known as a recessive allele. The offspring will not express the phenotype of the recessive allele if it is inherited together with a dominant allele, that is, the phenotype of the dominant allele will just be expressed.
