 
~~Brief Glossary~~

Agouti:
basic color of striped cats. Derives from the
striped coloring of each hair. |
| ~~~~~ |
Allele:
is one of the alternative forms of a gene that
may occupy the same position on two similar
chromosomes
determining alternative hereditary
characteristics.
Alleles that derive from the same gene are
grouped together in a series
(for example, a series is that which determines
black, chocolate, cinnamon). |
~~~~~
|
Cromosomi:
small bodies formed by DNA and proteins
transmitted by parents to children.
They carry genetic material. There are two for
each type
(a couple formed by two identical chromosomes
called homologous). |
~~~~~
|
Phenotype/Genotype:
phenotype is the physical aspect of an
individual, genotype is the genetic constitution.
For example, a phenotype black cat may have two
types of genotypes: AA or Aa |
Gene:
fundamental unit in genetic heredities: it is a
segment of DNA that codifies a function or a
characteristic.. |
~~~~~
|
Dominant Gene:
expresses its effect even if it is present with
another recessive allele.
A single dominant gene is sufficient for a
character to be expressed. |
~~~~~
|
Recessive Gene:
is unable to be seen if it is not present in both
members of the chromosome pair.
To be seen it must be present in two copies |

Note:
Some alleles have been left out because they are not
found in Devon Rex cats:
Hr/hr, corresponds to the lack of fur, which is found in
Sphinx cats.
L7l determines a long or short coat.
Wb/wb determines a golden color in tabbies which has yet
to be fully proven.
