The next focus for my new goldfish variety project is to construct the dragon eyes from the F1s. Since the F1s have recessive alleles for dragon eyes (Ee), I select only those with pearl scale features for inbreeding and linebreeding across different batches to create F2.

The Punnett chart for F2:

Very few (only 25% theoretically) of the F2 exhibits the dragon eyes (ee) features. The normal eyes F2 will not be used for next propagation as there is no way to tell if it is a pure normal eye (EE) or a normal eye that carries a recessive allele for dragon eye (Ee).

From the thousands, there are even fewer of those with both dragon eyes and pearl scale features. In order to get better breeders, I did numerous spawns using breeders from the F1 sublines just to get a few suitable F2 for the next propagation.

The problem of incomplete dominance for pearl scale seems prevalent even in the F2 as not many have good pearl scale properties.

1) F2 - in this batch, only 1 has dragon eyes (circa 2006).
