That is really cool looking! The yellow lips look really nice with the blue body. Beautiful! I know it is not an average, but it looks cool!
That is friggin awesome.
So, genetics.
If it's one gene controlling it, and it's dominant, when you breed this JD with a female you can either get 50% with this and 50% without, or 100% with this. If you get 50/50, then it doesn't matter what you breed your yellow-lipped offspring with, the father or their other yellow-lipped offsprings, as at that stage both pops and the yellow-lipped offsprings are heterozygous for this trait. If you get 100% yellow-lipped offsprings, then you know that dad is homozygous for the trait, and should breed a female offspring with pops.
If the gene is recessive, then you'll get 100% non-yellow-lipped fry, though they'd all be heterozygous. Crossing one with pops will yield 50/50 yellow-lipped/normal. Crossing them with each other will yield approximately 25% yellow-lipped. Either way once you obtain yellow-lipped fry, they'll continue to be maintained.
So basically:
100% yellow fry: Dominant trait, pops is homozygous, cross an offspring with pops.
50/50: Dominant trait, pops is heterozygous, cross a yellow-lipped offspring with pops or another yellow-lipped offspring. Does not matter.
0% yellow fry: Recessive trait, cross a yellow-lipped offspring with pops to yield the most amount of yellow-lipped in the third gen, crossing with another yellow-lipped offspring works, but yields less yellow-lipped offspring in the third gen.
