Everyone has the same number of introns; every allele of a gene has the
same pattern of introns and exons.
Well, more or less - there will be a few small mutations that interfere
with splicing, and larger mutations that take out or duplicate entire
genes or bits of genes, which will lead to variation, but not an awful
Anyway, i know of no evidence for a correlation between number of introns
Unless, of course, you mean across species. Short-lived, fast-reproducing
organisms tend to have fewer and smaller introns, since they slow down
