Assuming one is silver and the other is black lace and nothing else there will be 50% silver and 50% black lace.
If it's a zebra, and a black lace it will be 50% zebra, and 50% zebra lace. No black lace will appear.
Which is what I think it is.
It's a long road from eggs to identifiable patterns still though, they have to make it to juveniles, about 6-7 weeks from eggs. don't count the chickens, a lot can go wrong between now and 40 to 50 days from now. if those are the eggs on the filter box, the really white ones are bad and not fertilized, the translucent brown sort of ones are good.
Best of Luck!
