I already have a pair of 1 CT M and 1 VT F getting another pair to actually line breed :).

Initially I just thought about inbreeding the crown gene over 5 - 8 generations but then I would be strengthening other biologically weak traits. So then instead of breeding just a pair and making the genes weaker I thought of line breeding them and crossing each new generation by breeding 2 M to 2 F .

Initial Pairs : (G - Generation , M - Male , F - female)

1Fa , 1Fb , 1Ma , 1Mb

Breeding lines


1Fa + 1Ma = G1a (Use 1 M and 1 F from this generation)

1Fb + 1Mb = G1b (Use 1 M and 1 F from this generation)

Generational Crosses

G1aF + G1bM = G2a (Use 1 M and 1 F from this generation)
G1aM + G1bF = G2b (Use 1 M and 1 F from this generation)

G2aF + G2bM = G3a (Use 1 M and 1 F from this generation)
G2aM + G2bF = G3b (Use 1 M and 1 F from this generation)

G3aF + G3bM = G4a (Use 1 M and 1 F from this generation)
G3bF + G3aM = G4b (Use 1 M and 1 F from this generation)

And so on....until desired result is reached

A little off topic but probably what those guys would have done on the bettas but with 5+ pairs in a line.
