Diagram of intron 1 of selected catarrhine, platyrrhine, and prosimianDRB genes. The Alu elements identified in the intron are shown and their orientation is indicated by arrows. The distances between the Alu elements and the length of sequenced fragments in the 5‘ and the 3‘ ends of intron 1 are indicated by brackets. The shaded box represents a 870-bp deletion in the 3‘ end of intron 1. The drawing is not to scale.
