A short journal (JAN 27, 2016)
So, I got a share of some beautiful Albino Hi-fin Red coming today. They are still juveniles, but I should have enough time to wait for them ready because my new candidates are still young. Then I started pairing this way - Breeding model for P: 1, 2) Hi-fin Red Albino Male (♂: Hh DrDr pp) x Lo-fin Kohaku Albino Female (♀: hh Dr-Dr-[*] pp) then 3,4) is a reciprocal cross model of 1,2) as below 3,4) Hi-fin Red Albino Female (♀: Hh DrDr pp) x Lo-fin Kohaku Albino Female (♂: hh Dr-Dr- pp) Expectation: - I would expect to have F1 Hi-fin Red Albino-carrier (Hh DrDr- pp) from breeding model 1,2,3,4). Note that the Hi-fin Red Albino parents are siblings. And Lo-fin Kohaku Albino are cousins. Result: ... to be filled out Choosing F1 breeders: - Hi-fin individuals from F1 will be selected. - Dark red color is preferred. - Good growth rate and long maturity age are a plus. - Eventually, shape of Hi-fin and size of the fishes are matter. Note: If offspring quality between the two parallel lines [1 and 2] and [3 and 4] is not too difference, F1 breeder males will perform reciprocal cross to the other line's P Koi females. And a similar method would be apply for F1 breeder females x P Koi males. Breeding model for F1: 1, 2) Hi-fin Red Albino-carrier Males (♂: Hh DrDr- pp) x Lo-fin Kohaku Albino Female (♀: hh Dr-Dr-pp) then 3,4) is a reciprocal cross model of 1,2) as below 3,4) Hi-fin Red Albino-carrier Males (♀: Hh DrDr- pp) x Lo-fin Kohaku Albino Female (♂: hh Dr-Dr- pp) Expectation: - I would expect to have F2 Hi-fin Kohaku Albino-carrier (Hh Dr-Dr- pp) from breeding model 1,2,3,4). Note that from my last experiment done on Lyretail trait, F2 offpsring was not completely showing Kohaku model, thus required more work to improve Kohaku pattern continuing to F3 or further. Result: ... to be filled out Choosing F2 breeders: - Hi-fin individuals from F2 will be selected. - Dark red color and strong clear Kohaku pattern are preferred. - Good growth rate and long maturity age are a plus. - Eventually, shape of Hi-fin and size of the fishes are matter. [*] I assumed that Kohaku trait is the loss of red pigment on Dorsal, that's why I symbolized Koi trait as Dr- (Dorsal Red with negative sign)
