Question

Quizplus · Accepted Answer

Human chromosome 2 is the result of the fusion of two smaller chromosomes that are still present as separate chromosomes in our closest ancestral ape relatives. This is supported by genetic evidence, including the presence of telomere sequences at the fusion site and the existence of two centromeres (one of which is now inactive).
