The figure 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.
Which of the following statements describes the result of the movement of these blocks?
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.

The figure 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.
Which of the following statements describes the result of the movement of these blocks?
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.

Quizplus · Accepted Answer

The diagram shows that blocks of genes on human chromosome 16 have moved to four chromosomes of the mouse through chromosomal translocations. Therefore, choice D is the correct answer. Choices A and B are incorrect because they do not accurately describe the movement of the blocks of genes. Choice C is also incorrect because there is no evidence of the sequences represented duplicating multiple times.
