Final answer:
All the offspring from a homozygous brown fur mink crossed with a homozygous silver-blue fur mink will be brown, as brown is dominant. Therefore, none of the offspring would be expected to have silver-blue fur.
Step-by-step explanation:
In genetics, when a homozygous brown fur mink (which we can denote as BB) is mated with a homozygous silver-blue fur mink (bb), since brown fur is dominant over silver-blue fur, all the offspring would carry the dominant brown fur allele. This means all offspring would have a genotype of Bb, showing the phenotype of brown fur. Since none of the offspring can have a genotype of bb (which is required for silver-blue fur as it is recessive), you would expect none of the 8 offspring to be silver-blue in color.
