Multiple Choice

Figure 18.2
-Figure 18.2 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. What does the movement of these blocks in the genomes suggest?

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.
