  1. Intron position conservation was tested between 486 U{1:1} gene pairs (pairs in which both genes are supported by full-length transcript), and on random samples of 486 shuffled gene pairs from both species extracted fifty times from U{1:1} genes and from all nuclear genes. Intron position was based on the corresponding protein sequence alignments (ClustalW).
