Human chromosome 2 probably arose by means of a:
A)translocation
B)pericentric inversion
C)fusion of two ancestral chromosomes
D)break in a large ancestral chromosome

Question

Quizplus · Accepted Answer

Human chromosome 2 is the result of the fusion of two ancestral chromosomes. This is supported by the fact that human chromosome 2 has a large telomere sequence in the middle, which would have been the end of one of the ancestral chromosomes, as well as two centromere sequences, which would have been the centromeres of the two ancestral chromosomes. Translocations, pericentric inversions, and breaks in a large ancestral chromosome would not result in the specific characteristics observed in human chromosome 2.
