A cluster of genes on chromosome arm 2L with significant over-expression in the African population. Solid boxes represent transcriptional units, with the arrow indicating the direction of transcription. The African/European expression ratio of each gene, as determined by microarray experiments using males  and females (present study), is shown at the bottom. Expression of CG33307 was not detected in females.
