TAS Angelfish Naming Conventions Part 2
Phenotype Names

• A Presentation for The Angelfish Society
• by
• Tamar Stephens

Introduction

• This is Part 2 of a 2-part series.
• Part 1 explained what genetic notation is, and
  how the TAS genetic notation for angelfish of the
  species Pterophyllum scalare is structured.
• Part 2 explains the rules used by the TAS
  Genetics Calculator to create phenotype names
  from the genotypes.

3
Vocabulary refresher

• Genetic notation letters used to represent
  genes and alleles
• Phenotype - The appearance of an individual, such
  as smokey or zebra.
• Genotype - The genes that create a particular
  phenotype.

4
What does the Genetics Calculator Do?

• The calculator generates genotypes for any
  hypothetical crosses using the alleles programmed
  into the calculator.
• The calculator generates phenotype names for any
  genotype for parents and for offspring.
• This presentation will show you the rules used by
  the Genetics Calculator to create a phenotype
  name.

In Part 1 we saw how the Genetics Calculator
displays the genotype.

The genotype lists the alleles at each locus in
this order
1 Dark Locus (D, M, Gm, g)
2 Zebra/Stripeless Locus (Z,S)
3 Smokey (Sm)
4 Veil (V)
5 Half-black (h)
6 Pearly (p)
7 Albino (a)
8 Streaked (St)
7
But the phenotype name does not follow the same
order!
8
Phenotype names are created with a different
logic.

• Here are the Naming Rules

9
Phenotype names are based on the following
hierarchy.

• 1. albino
• 2. gold, gold marble, marble
• 3. streaked
• 4. zebra, smokey, chocolate, leopard
• 5. half-black
• 6. dark descriptions
• 7. Gm/
• 8. ghost, blushing
• 9. pearlscale
• 10. veil
• 11. common names that have stuck
• 12. exceptions

10
1. Albino (a/a)

• 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.
• Examples
• g/g a/a ? albino gold
• Gm/g a/a ? albino gold marble
• Sm/ - a/a ? albino smokey

Albino
11
2. Gold, gold marble, marble

• 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)
• Examples
• M/M a/a ? albino marble
• Gm/Gm a/a ? albino gold marble
• Gm/Gm /a ? gold marble
• M/g V/ ? marble veil

Gold Marble
12
3.Streaked - St/ or St/St.

• Streaked comes next if the fish contains St/ or
  St/St and has a dark allele (D).
• Streaked generally doesnt show in the phenotype
  unless a dark allele is present, so only use
  streaked if a dark allele is present.
• Examples
• D/ St/ ? Streaked black lace
• D/g St/St ? Streaked hybrid black
• D/D St/ ? Streaked double dark black

Streaked Black Lace
13
4. Smokey (Sm) combinations with or without Zebra
(Z)

• Zebra, smokey, chocolate or leopard will come
  next if the fish is Sm/, Sm/Sm with or without
  zebra.
• Examples
• Sm/ ? smokey
• Sm/ - a/a ? albino smokey
• M/ - Sm/ ? smokey marble
• Sm/Sm ? chocolate
• Sm/ - Z/ ? smokey leopard
• Sm/Sm Z/Z ? leopard
• Sm/Sm Z/Z - D/ ? leopard lace
• Z/ - a/a ? albino zebra

Smokey Leopard
14
5. Half-black (h/h)

• Half-black is added after the previous color
  mutations.
• Examples
• h/h ? half-black
• Z/Z h/h ? zebra half-black
• Z/Z h/h a/a ? albino zebra half-black

Zebra Half-Black (in foreground)
15
6. Dark allele (D)

• Dark allele descriptions follow half-black
• Lace for D/
• Hybrid black for D/g, D/Gm, and D/M
• Black (dd) or double dark black for D/D
• 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.

16
6a. Dark Allele (D) continued

• Lace is used for any phenotype with D/ at the
  dark locus.
• Examples
• D/ ? black lace
• D/ - Sm/ ? smokey lace
• D/ - Z/ - a/a ? albino zebra lace

Black lace angelfish
17
6b. Dark Allele (D) continued

• Hybrid black is used for genotypes with D/g,
  D/Gm, and D/M
• Examples
• D/g - S/ ? hybrid black ghost
• D/g - Sm/ ? smokey hybrid black
• D/Gm - h/h ? half black hybrid black

18
6c. Dark allele (D) continued

• Use Black (dd) or double dark black for D/D
• Example
• D/D Sm/ ? smokey black (dd)
• D/D Z ? zebra black (dd)

Smokey Black
19
6d. Dark allele (D) continued

• 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.
• Examples
• D/ - Z/ - h/h ? zebra lace half-black
• D/g Z/ - h/h ? zebra half-black hybrid
  black

7. Gold Marble

• 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/.
• Examples
• Gm/g - S/S ? gold marble blushing
• Gm/ - S/S ? blushing gold marble

Blushing Gold Marble (aka blue koi)
Gold Marble Blushing (aka koi)
21
8. Ghost and Blushing

• Ghost and blushing are added to the end of the
  name after the other color mutations. Ghost can
  be listed in parenthesis when its effect is
  questionable. (Marble, gold, gold marble and
  smokey.)
• Examples
• D/g S/ ? hybrid black ghost
• D/g S/S ? hybrid black blushing
• M/M S/ ? marble (ghost)
• M/M S/S ? marble blushing

Marble Blushing
22
9. Pearl Scale

• Pearlscale is added after all other color
  mutations if the fish is p/p
• Examples
• 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
23
10. Veil and Super-veil

• Veil is added at the end if the fish is V/ and
  super-veil if the fish is V/V.
• Examples
• g/g V/ ? gold veil
• g/g V/V ? gold super-veil

Gold super-veil
24
11. Common names that have stuck

• 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.)

25
12. Names that dont fit the rules - Clowns

• 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

Black Clown
26
Miscellaneous

• 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

27
What a lot to remember!

• Fortunately, you do not really need to remember
  all these rules.
• As you work with your own angelfish, you will
  become comfortable with the names that apply to
  them.
• If you do a cross that gives you a phenotype that
  is new to your experience, you can use the
  genetics calculator to help you figure out what
  to call it.
• Dont forget that the Phenotype Library is a
  resource to help you understand what most of the
  possible genotypes will look like.
