To determined quality you have to compare fish to established standards in which case your fish will not be of good quality.
Will they be petstore quality? Probably, because most petstore fish are bad quality.
First of all, combining tail types is a bad idea. You will get messy fins. Saying that you would get combtails is wrong, you will get delta fry with uneven web reductions.
Your female looks in no condition of spawning. She looks very small and thin. If you decide you're going to spawn her anyway, please give her a couple of months of good food and top water conditions to put some weight in her.
Your male is also not in spawning condition because he's sick with finrot.
Spawning takes a lot out of a pair and they must be at 100% before you attempt anything. Even what seem like healthy fish can drop dead soon after they spawn, that's how much of a toll it takes on them.
