Only answer if you know it?
If there is a 22 nucleotide base sequence difference for a gene found in both humans and penguins, what is the estimated mutation rate for that gene (your answer should be in #of mutations per million years). Use the phylogenic tree shown and SHOW YOUR WORK.

Part a - which gene to compare? in this exercise, you will use the cytochrome c oxidase i (coi) gene to investigate relationships among salmon species. (this gene encodes a protein that functions in the mitochondrial electron transport chain.) you will compare the coi gene sequences from your salmon test samples to the standard sequences for each salmon species. in order for the coi gene to be useful for distinguishing among the different salmon species, which three statements must be true?
