Yeah I'll let you have mutations, but when the sperm fertilises the egg and the zygote forms there is only one set of dna, which replicates. The DNA has to be indentical.
It has to be an environmetally factor, because if the differences were down to mutation then somewhere the world wouldn't there be to twins with indentical prints?? ARRRRGGH. This is doing my head in more than those stinky assed tenbury fuckas who inhabit my pub.
