-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?

Question

Quizplus · Accepted Answer

The movement of these blocks in the genomes suggests that chromosomal translocations have occurred, which means that blocks of sequences have been moved to other chromosomes. This is evidenced by blocks of similar genes on four different chromosomes of the mouse, which would not be present if the sequences had simply separated and returned to their original positions or if sequences within the blocks had become increasingly divergent. Additionally, there is no evidence of sequence duplication in the diagram.
