Answer:The genetic law that best explains the results of this cross is Segregation.
In Segregation, each parent has two copies of a gene, one from each parent, and each offspring receives one copy of the gene from each parent. In this cross between two mice with long tails and brown fur, the two genes for tail length (long or short) and fur color (brown or white) have separated, or segregated, during gamete formation, and each offspring has received one copy of each gene.
The fact that the offspring have different combinations of these genes (long-tailed with brown fur, long-tailed with white fur, etc.) suggests that the genes for tail length and fur color are located on different chromosomes and are assorting independently of each other, which is also in line with the law of Independent Assortment. However, the fact that the offspring display four distinct phenotypes (appearance) implies that the genes for tail length and fur color are dominant or recessive and not codominant, which would be seen in Incomplete Dominance.
