Answer:Using the mouse Pax6 gene as a baseline, determine the similarity of the homologous genes from the unknown species.
For each unknown species, determine the number of nucleotides that are different from the nucleotides found in the mouse sequence. There are 60 nucleotides in each sequence. To determine the percent similarity, subtract the number of different nucleotides from 60, divide the result by 60, and multiply by 100.
