Average gene expression increases with the number of introns in genes. The number of 5′ ESTs in each cluster was used to estimate expression. These 5′ ESTs were derived from primary libraries and so reasonably estimate mRNA abundance in the libraries. The greater the number of exons in a gene the greater its expression, as measured by the number of 5′ ESTs
