TAS Angelfish Naming Conventions Part 2 – Phenotype Names
A Presentation for The Angelfish Society
You can view Part 1 on the TAS website at:
Or look for it on the “Presentations” page at: http://www.theangelfishsociety.org/PresentationsTAS.htm
Here are the Naming Rules…
If the angelfish has the genotype a/a, it is simply an albino.
For any other genotype that includes a/a, “albino” will list first in the phenotype name.
g/g – a/a albino gold
Gm/g – a/a albino gold marble
Sm/+ - a/a albino smokey
Gold, gold marble, or marble will come next if both alleles at this locus are some combination of M, Gm, or g. (M/M, M/Gm, M/g, Gm/Gm, Gm/g, or g/g)
M/M – a/a albino marble
Gm/Gm – a/a albino gold marble
Gm/Gm – +/a gold marble
M/g – V/+ marble veil
Streaked comes next if the fish contains St/+ or St/St and has a dark allele (D).
Streaked generally doesn’t show in the phenotype unless a dark allele is present, so only use “streaked” if a dark allele is present.
D/+ – St/+ Streaked black lace
D/g – St/StStreaked hybrid black
D/D – St/+ Streaked double dark black
Streaked Black Lace
Zebra, smokey, chocolate or leopard will come next if the fish is Sm/+, Sm/Sm with or without zebra.
Sm/+ - a/a albino smokey
M/+ - Sm/+ smokey marble
Sm/+ - Z/+ smokey leopard
Sm/Sm – Z/Z leopard
Sm/Sm – Z/Z - D/+ leopard lace
Z/+ - a/a albino zebra
Half-black is added after the previous color mutations.
Z/Z – h/h zebra half-black
Z/Z – h/h – a/a albino zebra half-black
Zebra Half-Black (in foreground)
Dark allele descriptions follow half-black
Lace is used for any phenotype with D/+ at the dark locus.
D/+ black lace
D/+ - Sm/+ smokey lace
D/+ - Z/+ - a/a albino zebra lace
Black lace angelfish
D/g - S/+ hybrid black ghost
D/g - Sm/+ smokey hybrid black
D/Gm - h/h half black hybrid black
Use Black (dd) or double dark black for D/D
D/D – Sm/+ smokey black (dd)
D/D – Z+ zebra black (dd)
Because half-black lace sounds strange, the lace was placed before the half-black for half-blacks with D/+. Other dark combinations like hybrid black and clown black were placed after the half-black.
D/+ - Z/+ - h/h zebra lace half-black
D/g – Z/+ - h/h zebra half-black hybrid black
To differentiate gold marble Gm/Gm and Gm/g from angelfish with Gm/+, gold marble will be added as the final “color” mutation description if the fish is Gm/+.
Gm/g - S/S gold marble blushing
Gm/+ - S/S blushing gold marble
Blushing Gold Marble (aka “blue koi”)
Gold Marble Blushing (aka “koi”)
D/g – S/+ hybrid black ghost
D/g – S/S hybrid black blushing
M/M – S/+ marble (ghost)
M/M – S/S marble blushing
g/g – p/p gold pearl scale
D/+ - Sm/+ - p/p smokey lace pearl scale
h/h – p/p half-black pearl scale
Gold Pearl Scale
Veil is added at the end if the fish is V/+ and super-veil if the fish is V/V.
g/g – V/+ gold veil
g/g – V/V gold super-veil
Several common names are in wide enough usage that the calculator was programmed to provide that name.
S/Z silver clown
D/+ - S/Z clown black
Gm/Gm - S/S or Gm/g – S/S koi
D/+ - S/S turquoise
Sm/+ - Z/+ or Sm/+ - Z/Z smokey leopard
Sm/Sm – Z/Z or Sm/Sm - Z/+ leopard
D/D – S/S, D/g – S/S black velvet (any form of black blushing)
Gm/+ S/S* blue koi
(*Gm/+ - S/S is commonly referred to by many people as a “blue koi” but the genetics calculator calls it “blushing gold marble.”)
Z/S silver clown
With D/D or D/g the fish is darker and the clown markings are harder to see, so “black” precedes “clown.”
D/g – Z/S hybrid black clown
D/D – Z/S black clown
With D/+ the clown markings are more apparent, so “clown” precedes “black to distinguish the phenotype from a black clown.
D/+ - Z/S clown black
The Genetics Calculator will not give names based on alleles that do not show in the phenotype. For instance, Gm/Gm, Gm/g, and g/g are epistatic (suppress the expression) to smokey, halfblack and zebra.
Thus, with a single dose of gold marble, both gold marble and smokey will show in this genotype:
Gm/+ - Sm/+ smokey gold marble
But with Gm/Gm, Gm/g, or g/g the half-black, smokey or zebra alleles do not show up in the phenotype, so the names are simply:
Gm/Gm – Sm/+ gold marble
Gm/g – h/h gold marble
g/g – Z/Z – h/h gold
