| Gene |
The basic unit of genetics, Genes
come in pairs, one supplied from each parent. Each gene pair
determines one specific trait. There are thousands of gene
pairs in each strand of DNA. |
| Genotype |
A description of the genes in
one individual, may include recessive traits where only one
gene is present. ie Het Albino |
| Phenotype |
Visual description of animal,
excludes any non visual genes ie, the same "Het
Albino" Genotype would be "Normal" for the Phenotype.
|
| Mutant Gene |
Any gene that is different
from the corresponding normal gene. Not necessarily a visual
mutation. |
| Wild Type or Normal |
A snake (or trait) that looks
like most of the snakes found in the wild. Also used to
describe any individual gene that when paired up with a
similar gene would produce a snake that, for that individual
gene trait, would look like most of the snakes found in the
wild. |
| Heterozygous (Het) |
Having two
different genes within a gene pair. Most commonly one normal
and one mutant but could be two different mutant genes.
|
| Homozygous |
Having both genes within a
gene pair the same. Can be normal or mutant. |
| Super |
Slang term commonly used when a
snake has a gene pair that is Homozygous for either a
dominant or incomplete dominant mutant gene. |
| Trait |
Physical appearance that it
distinguishable from the normal physical appearance. |
| Recessive Mutant Gene |
Trait is only
expressed when the gene pair is Homozygous for the specific
mutant gene. |
| Dominant Mutant Gene |
A mutant gene that
has it trait expressed when the gene pair is either
heterozygous or Homozygous for that specific mutant gene.
Heterozygous and homozygous specimens are not 100%
distinguishable from each other. Note, with some dominant
traits some of the specimens can be visually identified as
heterozygous or homozygous. |
| Incomplete Dominant Mutant Gene |
Similar to “dominant
mutant gene” except there are three distinct expressions,
normal, het and Super. The three different levels can be
distinguished from each other 100% of the time. |
| Co-Dominant Mutant Gene |
Term often misused to describe
Incomplete Dominant. Is correctly used to describe a
physical trait that is expressed by two different genes on
the same location. example: Paradigm in BCI is one
Sharp Albino gene paired with one Boawoman Caramel Gene
producing an animal visually different from Normal,
Albino or Caramel. |
| Double Het (DH) |
Two gene pairs
where one gene in each pair is normal and the second gene is
a mutant gene. I.e. double heterozygous for snow would have
a normal gene paired with an albino gene and a normal gene
paired with an anerythristic gene. |
| Triple Het (TH) |
Same as double
heterozygous except applies to three gene pairs. |
