**= Colors =**
Standard - Our Classic Grey Glider. There are some variations within it
ranging from very dark(Black Beauties) to Reddish Tones(Cinnamon, Lion, etc.)
to lighter hues(Buttercream, Strawberry, etc.)
= Patterns =
White Face - A glider that lacks the dark ear bars.
Mosaic - A sugar glider with various white patches & markings. There are
several mosaic variations: White Mosaic, Ringtail Mosaic, Piebald Mosaic, etc.
= Recessive Colors =
Leucistic - A leucistic is a white sugar glider with black eyes. Also called a
Black-Eyed White(BEW).
Albino - An albino is a white sugar glider with red eyes. Also called a T-
albino.
Cremino - A cremino is an off-white sugar glider, with light cream markings and
burgundy eyes. Also called a T+ albino.
Platinum - A silvery/taupe colored sugar glider that often has a reduced/thin
stripe. There are two Platinum lines - Haley & Silverbelle. The Platinum
& Leucistic genes can interact to produce a Platinum glider.
= Other Colors/Patterns =
White Tip - A sugar glider with a white tip on it's tail.
= Genetics =
Recessive Inheritance: ExampleDominant: The offspring show the color if they get
the gene and
you only need one of a certain color parent to pass it. One - Both parents
mosaic and one
standard can produce mosaic joeys. The babies that are not mosaic will not
carry
the mosaic gene. White face is the same, if it shows it's there. If it doesn't
show
it's not there.
Dominant Inheritance Example: One parent (Ff) has a dominant color gene (F).
This gene over rides the normal color gene (f). The parent shows the dominant
color. When mated with a normal color sugar glider (ff) the offspring either
get
the color (Ff) or do not (ff). There are no carriers. If the gene
(H) is present it
shows. (mosaic and a white face)
Recessive: Gliders that inherit two copies of the recessive color gene (h).
They are (Hh). The parents will show the normal
color. Offspring carry (Hh), do not carry (HH), or show (hh) recessive color.
However, a glider that inherits only one copy of the color.
Example Two - recessive gene will be a carrier for it and can pass that gene
along to its offspring. Physically, they will look like a standard grey glider.
Recessive Colors include Leucistic, Platinum, Albino, and Cremino.
Recessive Inheritance Example: Both parents are carriers (Hh) Their genotype
consists of the dominant wild-type (H) and the recessive (h). Their
phenotype(or physical appearance) is that of the dominant wild-type
color(standard grey).
Another Example: One parent shows the recessive color gene (hh) and one parent
is normal color (HH). ALL offspring will carry the recessive gene (Hh) because
the parent that shows the color only has that gene to pass.
More about recessive is below.
Dominant is pretty easy. The offspring show the color if they get the gene and
you only need one of a certain color parent to pass it. One mosaic and one
standard will have mosaic babies. The babies that are not mosaic will not carry
the mosaic gene. White face is the same, if it shows it's there. If it doesn't
show
it's not there.
Dominant Inheritance: Example - One parent (Ff) has a dominant color gene (F).
This gene over rides the normal color gene (f). The parent shows the dominant
color. When mated with a normal color sugar glider (ff) the offspring either get
the color (Ff) or do not (ff). There are no carriers, if the gene is present it
shows. (mosaic and white face)
Recessive Colors: Leucistic, Albino, and Cremino
Dominant Patterns: Mosaic and White Face
Colors with Unknown Inheritance: White Tip
Het: Het is short for heterozygous, and means possessing two different forms of
a particular gene, one inherited from each parent. In this case we are talking
about the color gene. A het is a normal color glider that carries a recessive
color
gene.
Possible Het: A normal color sugar glider that has a chance to carry a recessive
color gene.
= Recessive Breeding =
This is the most confusing part of color breeding. Recessive breeding is where
we get hets and possible hets. Recessive colors include leucistic, albino,
cremino, & pure platinum(from non leu lines). The following information
applies to all of them but I will use leucistic
as my example color. Normal applies to any sugar glider that is not from the
leucistic line.
----
Leucistic + Leucistic =
* Leucistic (always)
Notes: It is my opinion that this kind This type of breeding should
never be done. The bloodlines of our leucistics are not
spread out enough to support it. is often discouraged as it will produce only
the recessive colored gliders. While we haven't seen issues such as
"lethal whites" in the glider community, out-crossing is always
preferred.
----
Leucistic + 100% Leu Het =
* Leucistic (50% of the time)
* 100% Leu Het (50% of the time)
Notes: It is my opinion that This cross should be done after carefully analyzing
the lines & pairings. The lines are more spread out where there may be
acceptable pairings of this kind of breeding should
never be done. The bloodlines of our leucistics are not
spread out enough to support it. nature.
----
Leucistic + Normal =
* 100% Leu Het (always)
Notes: This is breeding out, and a recommended pairing.
Normal All Normal color offspring. offspring that are carriers for the
leucistic gene.
----
100% Leu Het + 100% Leu Het =
* Leucistic (25% of the time)
* 100% Leu Het (50% of the time)
* Normal (25% of the time)
Notes: Approximately 1 in 4 offspring will have the recessive color.
3 in 4 offspring will have the normal color.
2 in 3 of the normal color offspring will have the recessive
color gene. These gene, which is why the standard grey colored offspring are
sold as having 66% hets as they have a 66% 66%(2 out of 3) chance
of having the leu gene. This is not breeding out and is
not a recommended pairing.
----
100% Leu Het + Normal =
* 100% Leu Het (50% of the time)
* Normal (50% of the time)
Notes: This is breeding out, and a recommended pairing.
Normal Normal color offspring, sold as 50% possible leu hets.

= Probability of a Carrier Inheritance Chart =
Breeders can use
[http://sugarglidergenetics.weebly.com/breeder-reference-chart.html this chart]
to determine the likelihood a particular sugar glider is a carrier(often
referred to as a het or heterozygous individual) for a color gene. The percent
het is the probability, or chance, that the offspring will inherit the designed
gene. A glider will either inherit the gene, making it a 100% het(aka a carrier
for the gene) or it won't. For example, if you have a 33% het, the probability
of that glider inheriting the gene is 33% while it has a 66% + 66% = 33%
* 66% + Normal = 33%
* 66% + 50% = 25%-33%
* 50% + 50% = 25%
* 50% + Normal = 25%
If any possible chance of not carrying it. You will need to carefully choose a
pairing to prove out if the glider is indeed a carrier for the gene or not. Once
the color is produced by a particular pair, you have proven your gliders carry
the gene and records should be changed to reflect "100% het pairing
produces (proven)".
A [http://sugarglidergenetics.weebly.com/new-color-calculator.html color
calculator] is also available - this can calculate the probability standard grey
offspring inherit the recessive color gene & a leucistic both parents
are then 100% hets. few other neat things.
