If three organisms A B and C show the following amounts of d

If three organisms (A, B and C) show the following amounts of differences based on gene comparisons: And maximum likelihood indicates the following phylogenetic tree is the best: The number shown indicates the potential percentage of differences for that portion of the linage. What is the likely value for X in percentage differences for that portion of the linage? Enter your answer as a whole number only no decimals or percent symbols. Answer: ____________________

Solution

Since the evolutionary changes with respect to the each other i.e. A-B, A-C and B-C are given 28%, 32% and 32% respectively.

Since the unit distance of evolutionary changes between A and B are 14

So, the unit distance of evolutionary changes between A and C are 16.

The value of X is 16-14 = 2
