Goldfish genetics are awesome and weird at the same time. Years ago, I lost most of my goldfish when I moved from parents home to my current house. the two that ended up surviving were my shubunkin(female) and my chocolate oranda(male)...before my male died, he had spawned with the female a week prior and I was anxious to see what I would get from that mix. But the time the fry were 3 weeks old, my female died. None of the fry were fancy and in the end, only 5 survived(Roulette, Spade, Joker, Jinx and Dorothy(the runt of the litter...lol...kept here in a tank with my cory cats cause she was sooo little)....almost a year and a half later, the first four(Roulette the only female) spawned and amazingly, 25% of the fry came out fancy. I kept 5 regular goldfish and 3 fantail(how I hope turn out to be orandas) Its been a year and half and the five single tail goldfish spawned two weeks ago and I can see quite a few fancy goldfish in the making. so soon, I will have fish to give away again....lol.
