There is no way of telling if the plants your seeds came from have hermaphroditic tendencies, or if your friend just had them in less than ideal conditions. There are many things that can cause a female plant to produce male anatomy. You won't know if your seeds will herm or not until you grow them out. Just keep a close eye, check all nodes for male pre flowers. Even late into flowering pollen can be produced. Keep on growing and keep a close eye on your girls, and you'll come out just fine. Respect
