Tisere fictional genetic system
The Tisere Genetic system
With over half a million possible genotypes
How it works
Each locus is a place on a chromosome where variation can happen. Each locus is labeled with a letter and the word locus. At every locus, there are different versions of a gene. These versions are called alleles. Different alleles can produce different traits, or phenotypes.
Some alleles are dominant. This means if an individual has that allele, it will show up in their traits. Other alleles are recessive, meaning they are only expressed when no dominant allele is present.
When a child is formed, alleles are passed down through recombination. Each parent gives one allele for each locus. That way, every individual has two alleles per locus (except on the sex chromosomes, which are a special case but not relevant here).
If both alleles at a locus are the same, the individual is homozygous. If the alleles are different, the individual is heterozygous. Sometimes, when alleles are different, the traits mix or both show up. This is called incomplete dominance or codominance. Not all alleles act this way—only certain ones.
Colors
B locus base color
B black
Br red
b brown
Red
Reset/Red base
Ginger dilution
Cream marking color
Brown
Chocolate base
Brown dilution
Sand marking color
Black
Black base
Gray dark dilution
Grey light marking color
D locus dilution
D wild type
d dilute
The expression of d makes non-marking areas the dilution color
I Locus iridescence
I iridescent
i non-iridescent
Iridescent, and it’s sheen modifiers covers completely black base and effect no other areas including black, dilution, and black marking color
S locus sheen
S Scarlett
Sg green
SB blue
Sv Violet
T locus Beak&Talon color
T copper/gold
tg yellow/pink
t silver/black
K locus beak&talon modifier
K yes
k no
No Yes
silver = gray/black
Gold = Copper
Pink = Yellow
E locus eye colors
E black
Ey yellow
Eg green
Eb blue
Incomplete dominant
Ey/Eg gold
Ey/Eb brown
Eb/Eg teal
E is completely dominant over other eye colors
Color shapes
A locus marking presence
A no markings
a markings
M locus Marking type
M Check
Mb Bar
mc unnamed, new mutation
m Tiping
Y locus Dark light swap
Y unaffected
y affected
Affect markings are paler than rest of body if no marking is present, individual is marking color
No effect markings are darker than the rest of body if no marking is present the individual would be base or dilute
W locus Wight
Wb/Wd White blanket
W speckled homozygous lethal
Ws wight Small
Wc Color
W locus expression, descriptions
WW born dead or not born at all
WbWb completely white
WsWs underbelly Undertale, and some of under wings are white. The rest of the individual is color
WcWc no white visible
WbWc
The face in her wing inner tail and underbelly are white
WWc
An area under the eyes has a small amount of white underbelly has small white speckles
WSWC head top of wing top and inner wing are all white
WSW the spots on the breast are bigger than WWC
WSWB has saddle, marking, may have some variation due to development
WBW looks completely white and you can’t tell whether it has a W or not which can be dangerous so common convention says if Tisere are completely white, they should not have children with each other
G locus Grizzle
Gs grizzle splotched
Gb grizzle Blizzard
Gn no grizzle
g grizzle tiger
Incomplete dominant
Gn + Gb = powder
Body shape
C locus Crest
C of
c on
Back of head feather(s)
F locus Feathered feet
F no
f yes
feet feathers may grow at different places on the feet
In function of Tisere reproduction I would like to note that birds sex chromosomes work in reverse from humans. There is the Z chromosome two copies of which equals male and one copy of which plus the female W chromosome equals a female.

Tisere lifecycle
Blood-born
A male and a female Tisere, working together, can make a Blood-Born Tisere egg. A Blood-Born egg, a fertilized egg, has an incubation period of 6 months. However, the egg stays fertilized in the mother for three month and then the egg is laid and will take 6 months to hatch. Females will not have recovered from her egg laying in order to have another for at least a year.
