The arms of human chromosome 2 are syntenic with two different chimpanzee chromosomes.What mechanism could have caused this pattern of synteny?
A)an inversion in the human chromosome
B)an inversion in one of the chimpanzee chromosomes
C)gene duplication in the human chromosome
D)exon shuffling in the chimpanzee chromosomes
E)a translocation involving two chromosomes

Question

Quizplus · Accepted Answer

The pattern of synteny between the arms of human chromosome 2 and two different chimpanzee chromosomes is most likely due to a translocation event involving two chromosomes. This event fused two ancestral chromosomes present in the common ancestor of humans and chimpanzees to form the single human chromosome 2, while in chimpanzees, these chromosomes remained separate.
