Question

A biologist sequences a gene shared by five different species. The percentage of sequence similarity for four different gene segments, A, B, C, and D, are shown in the table.

Answer 1

The correct pattern is the following:

a - 1

b - 4

c - 3

d - 2

e - 5

Species with more resemblance in their genes composition are closer, while species with the most differing gene composition are farther in the cladogram.
