YP eggs will appear cream or whitish as they are in the water. To tell if they are fertilized pull a small piece off the ribbon or look at the ribbon closely. If the centers are amber or clear-yellow colored they are fertile if the centers are white they were not fertilized. You may see amber and white egg centers in the same strand indicating partial fertilization of the strand and due to too few males. As the eggs develop after 5-7 days the centers will appear dark due development of the eyes on the embryo.
