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? In order for the COI gene to be useful for distinguishing among the different salmon species, which three statements must be true?a) The COI gene must be conserved enough that the sequences can be aligned for comparison. b)The COI gene must not contain any insertions or deletions. c)The COI gene must be present in Pacific salmon but not in Atlantic salmon. d)The COI gene must be variable enough that there are at least a few differences between each salmon species. e)The COI gene must be conserved enough that the same PCR primers work for all the species being tested
