If her DNA is not included, then a baby swap could be possible. Meaning any kid matching Danielynn's description could be brought in for the DNA test. In that case the baby would show she is not Larry's, which he surely would fight off in court. I'm sure they have her DNA to avoid that possibility, they kept it for a reason. I read somewhere that Howard's DNA was not tested. I don't know if that is true. But, if true, that wouldn't do Dannielynn justice. Because if it turns out Larry is not the father, but someone else is, that would leave Howard as the default father, cause his name is on the birth certificate. Well, at least that I think. :)
