在非洲绿色猴基因组中，总DNA的20%由高度重复的DNA序列组成，该序列主要以172个碱基对长度的重复单元的长串联阵列形式出现。狒狒的DNA含有与该重复单元同源的序列。然而，在狒狒基因组中，这些序列约占总DNA的6%，并以规则的方式与可能与猴子重复单元远亲的DNA片段交替。狒狒中与猴重复单元同源的序列包含在狒狒的高度重复DNA部分的340个碱基对重复单元内。两个物种之间同源重复序列的核苷酸差异程度估计为约10%。
In the African green monkey genome, 20% of the total DNA consists of a highly reiterated DNA sequence that occurs largely in long tandem arrays of a repeat unit that is 172 base-pairs in length. The DNA of the baboon contains sequences homologous to this repeat unit. However, in the baboon genome, these sequences comprise roughly 6% of the total DNA and alternate in a regular fashion with a DNA segment that may be distantly related to the monkey repeat unit. The sequences in the baboon that are homologous to the monkey repeat unit are contained within a 340 base-pair repeat unit of the highly repeated DNA fraction of the baboon. The extent of nucleotide divergence of the homologous repeated sequences between the two species is estimated to be about 10%.
