The genetic law that best explains the results of this cross is 'Incomplete dominance'.

## Step 1<br />The problem presents a scenario where two mice with long tails and brown fur are crossed, resulting in four different types of offspring: long-tailed with brown fur, long-tailed with white fur, short-tailed with brown fur, and short-tailed with white fur.<br /><br />## Step 2<br />The four types of offspring suggest that the traits for tail length and fur color are not strictly dominant or recessive. Instead, the traits seem to blend, resulting in a variety of combinations.<br /><br />## Step 3<br />This blending of traits is indicative of the concept of incomplete dominance. Incomplete dominance is a genetic principle where neither allele is completely dominant over the other, resulting in a phenotype that is a blend of the two.<br /><br />## Step 4<br />In this case, the blending of traits is seen in the offspring, where the traits for tail length and fur color are not strictly dominant or recessive. Instead, the traits seem to blend, resulting in a variety of combinations.
