The number of genes with single promoter among non-alternatively spliced genes.

Note. The vast majority of the non-alternatively spliced genes have a single promoter. All: the number of all the non-alternatively spliced genes. Genes with single promoter: the number of genes with single promoter among non-alternatively spliced genes. P-value: the probability that an observation (non-alternatively spliced genes with single promoter) is made by chance, is calculated using the cumulative Hyper-geometric Distribution.
