The markers in CODIS (law enforcement DNA database) don't cover the whole genome. The markers sold by commercial genetic genealogy databases also don't typically cover the whole genome. The likelihood of the few in utero polymorphisms occurring at one of the covered markers is very low. That means a whole genome would need to be sequenced to determine which twin DNA evidence came from.
