Inheritance Basics
Terminology
heterozygous (het.)- Two different alleles
at a single locus.
Example: Heterozygous albino is
Aa. This means the boa has one wild type gene (A)
and one albino gene (a).
homozygous (homo.)- Two identical alleles at
a single locus. Boas referred to as "supers" are homozygous. A
super hypo has two hypo genes.
Example: Homozygous albino is aa. This means the
boa has two albino genes (a).
wild type- The typical form of an
organism as it most frequently appears in nature (i.e. a normal boa). Wild type
boas have a normal phenotype and a normal genotype.
In genetics, the dominant gene is traditionally
symbolized with a capital letter. The genotype of a heterozygous albino boa is
displayed as
Aa.
This means one wild type gene (A) and one albino gene (a) since wild type is
dominant over albino. A heterozygous hypomelanistic boa is displayed as
Hh.
This symbolizes one hypomelanistic gene (H) and one wild type gene (h) since hypomelanism is dominant over wild type.
The percentages below apply to all simple
recessive, dominant, and co-dominant/incomplete dominant traits. You may
substitute traits inherited in the same manner and use the same percentages
below. For example, you can exchange albino with blood, or exchange motley with
aztec.
Abbreviations
anerythristic-
anery
hypomelanistic- hypo
double heterozygous (DH)- Heterozygous for two traits. For
example, a boa that is het. albino and het. Type I anery is DH snow.
triple heterozygous (TH)- Heterozygous for three traits.
Punnett Square
Genetic outcomes can be derived using a Punnett
square. The example is a breeding between a het. albino (Aa) and a het. albino (Aa).
Each parent has the same genotype (Aa). This means each parent has one wild type
gene (A) and one albino gene (a). Each baby will receive one gene from each
parent. The possible genotypes are shown in the example.
By breeding a heterozygous albino boa to another heterozygous albino boa, the
litter should yield the following:
25% albino (aa)
50% het. albino (Aa)
25% wild type (AA)
The wild type and heterozygous albino boas will all have the same wild-type
phenotype, but they will have differing genotypes. Since they are
indistinguishable in appearance, all the wild-type phenotypes from this breeding
are referred to as "66% possible heterozygous albino" since 2 in every 3 (or
66.6%) should be heterozygous albino.

The first line (bold
and underlined) details
the genetics of the breeding pair. It does not matter which is female (dam) and
which is male (sire).
The following lines
(not bold or underlined)
show the scientific probability for the offspring. In this example, 50% of the babies should
be hypo het. albino. The other 50% should be wild type het. for albino.

Some interesting notes on paradigm genetics:
One of the
most interesting aspects of this morph is
that you produce more Paradigms from a Sharp X Boawoman breeding than from a
Paradigm X Paradigm breeding. Also, there cannot be a Boawoman het. Sharp or a
Sharp het. Boawoman. Any boa with both genes is a Paradigm.
Here is the math for a Paradigm x Paradigm:
Sire can pass Sharp (a) or Boawoman (b).
Dam can pass Sharp (a) or Boawoman (b).
Your outcomes:
25% aa (Sharp albino)
25% bb (Boawoman)
50% ab (Paradigms)
Now, in a Sharp x Boawoman breeding:
Sire can pass Sharp (a) or (a).
Dam can pass Boawoman (b) or (b).
Your outcomes:
100% Paradigm (ab)
