| | Human and Ape Chromosomes |
 | | The four species have a similar number of chromosomes, with the apes all having 24 pairs, and humans having 23 pairs. |
 | | Chromosomes 3, 11, 14, 15, 18, 20, and Y look the same in three of the four species (those three being gorilla, chimps, and humans), and chromosomes 1, 2p, 2q, 5, 7 - 10, 12, and 16 are alike in two species. |
 | | The biggest single chromosomal rearrangement among the four species is the unique number of chromosomes (23 pairs) found in humans as opposed to the apes (24 pairs). |
