Question

refer to the table from question 9: in this hypothetical example, assume scientists determined that this sequence accumulates 2 mutations per year. use the nucleotide changes to determine the evolutionary distance between viruses b and e. 84 82 78 80

Explanation:

Step1: Identify nucleotide - change value

From the table, the number of nucleotide changes between viruses B and E is 160.

Step2: Calculate evolutionary distance

Since the sequence accumulates 2 mutations per year, the evolutionary distance $d=\frac{160}{2}=80$.

Answer:

80
