Cross breeding fin types - Probabilities
Assuming each breeder has true genes
PK x VT =
Because VT is dominant over all other types you will probably produce mostly VT
Because rounded caudal is dominant, there would also be some RT – one of the “inbetween types
There would also be other inbetween types – too long for a PK but too short to be anything else
Though recessive towards VT, you might still get a few traditional PK.
Long fin is dominant = L L
Short fin is recessive = l l
PK x HM
= (assuming both have true background)
This varies a bit depending on the type of PK.
(180* caudal, 2- 4 rays, half circle dorsal, long pointed anal fins – unequal fins)
DeT and HM (both perfect but mostly rounded edges – and both long and equal anals), HM with shorter fins, in between fins (probably including round tail), a few traditional PK
(180* caudal, 4-8 rays, half circle dorsal with long front rays, long rounded anal)
DeT and HM both long and balanced anals, in between fins (too short to be HM but too long for a PK, DeTPK and HMPK with or without HM marking (HM type of anal),
(180* caudal, 4-8 rays, extended dorsal with long front ray, equal anal)
DeT and HM with balanced fins, balanced HM with shorter fins, in between fins, symmetrical PK
PK x long finned CT
CT is recessive, Short fin is recessive;
100% will be CT-geno. Physically there will be little to no CT with equal web reduction (apparent at older age)
, inbetween short and long finned (most should be long finned), some comb tail (slight web reduction - short or long).
regular tail (dominant) = CC
Crown Tail (recessive) = cc
long finned (dominant) = LL
short finned (recessive)= l l
CTPK x CTPK = F3 = 100% CTPK
PK x long finned DT
DT is recessive, Short fin is recessive;
Similar to the CT, there should be 100% DT-geno. Physically fin length result is similar to PK x HM spawn. Most would be long single tails, long to short fins, some have uneven caudal lobes and long dorsal, some may have one caudal lobe but longer dorsal.
VT x DeT
VT is diminant over HM, thus results should be long finned; VT, VT with slightly wider spread, round tail, delta tail, NO HM, some Rose carriers (VT x Rose)
VT x HM
VT, VT with wider caudal, RT, DeT.
VT x Rose
VT, VT with wider caudal, RT carrier, DeT, SdeT/HM
It is best to wait until F1 is 6 months before continuing your line.
VT x CT
100% CT-geno; VT, with or without CT markings, VT-CT geno with wider spread, delta tail with or without web reduction, Comb VT or delta , There should be No equal web reduction,.
VT x DT
100% DT-geno ; Regular VT, VT with uneven caudal lobes or with longer dorsal, single tail VT with longer dorsal, regular VT, VT with wider spread.
*** If the DT were delta or HM, there would also be delta tail with or without DT markings.
DeT x HM
= mostly DeT, a few HM
DeT x Rose
= DeT, HM, Rose
HM x HM
= DeT, HM
8 ray HM x 8 ray HM = HM, Rose, DeT
HM x Rose
= Rose, HM, DeT
HM x CT
= (assuming both are SDeT or HM)
100% CT-geno - Delta and HM with or without web reduction.
HM x DT
100% DT-geno – Single Tail DeT and HM, Single tail HM and Delta with or without longer dorsal, DT with unequal caudal lobes.
CT x DT
Web reduction is recessive against full webbing;
Double lobes is recessive against single tail
CTDT geno’s – Single tail HM and Delta with or without CT and DT markings.
Regular = CC
Crown Tail = cc
Crown Tail Geno = Cc
Single Tail = DD
Double Tail = dd
Doublt Tail Geno = Dd
Crown double tail x crown double tail = ccdd x ccdd = 100% CTDT
