In a representative sample of primate species, including simians (Catarrhini and Platyrrhini) and prosimians (Lemuriformes and Lorisiformes), high-resolution, early replication banding revealed a homoeologous early replicating segment at the ends of both sex chromosomes. The DXYZ2 element, a repeated sequence specific for the human pseudoautosomal region, is conserved in the genomes of all primate species studies and is specifically localized in the distal early replicating segments of the X and Y chromosomes. Thus, cytogenetic and molecular evidence is presented of a highly conserved sex-chromosomal segment in primates. The pseudoautosomal behavior of this segment is discussed.
在一个包括猿猴（狭鼻猿和阔鼻猿）和原猴（狐猴型亚目和懒猴型亚目）的灵长类物种代表性样本中，高分辨率的早期复制带型显示在两条性染色体末端存在一个同源的早期复制区段。DXYZ2元件是人类拟常染色体区域特有的重复序列，在所有研究的灵长类物种基因组中都保守，并且特异性地定位于X和Y染色体的远端早期复制区段。因此，提供了灵长类中一个高度保守的性染色体区段的细胞遗传学和分子证据。讨论了该区段的拟常染色体行为。
