The dominant must be for the black fur and the recessive must be for the white fur.
Explanation:
<h2>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 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.</h2>
