Use the following figure to answer the next few questions.

Figure 21.2
Figure 21.2 shows a diagram of blocks of genes on human chromosome 16 and the locations of blocks of similar genes on four chromosomes of the mouse.
-The movement of these blocks suggests that
A) during evolutionary time, these sequences have separated and have returned to their original positions.
B) DNA sequences within these blocks have become increasingly divergent.
C) sequences represented have duplicated at least three times.
D) chromosomal translocations have moved blocks of sequences to other chromosomes.
E) higher mammals have more convergence of gene sequences related in function.

Quizplus · Accepted Answer

The movement of the blocks of genes suggest that chromosomal translocations have occurred, moving blocks of sequences to other chromosomes. The diagram shows that the blocks on human chromosome 16 correspond to blocks on multiple chromosomes of the mouse, indicating that the blocks have been moved.
