__NOTOC__Creatures in Project Gorgon using the [[Genetics]] system have genes which control their physical appearance, stats, and abilities. These attributes can be modified by either one gene or a collection of genes. A single gene can also influence multiple attributes. <br>A creature’s genes are organized into ten chromosomal chromosome rows, each with up to ten groups of four genes. All creatures of the same anatomy type share a map of possible genes and numbers of groups per chromosome. === Gene Terminology ======== Notation Styles ====='''In-Game Notation''': How genes appear in-game. Uses <three symbols here>. '''Text-File Notation''': How genes appear in exported text files. Uses D,R,x '''Player Notation''': A method developed by Animal Husbandry players. Uses X,o,t===== Genes: =====Genes are two-part genetic markers which influence the attributes of a creature. Every gene can be '''Dominant''', '''Recessive''', or '''Mixed ''' based on its two halves. '''Dominant''' genes: '''Dominant''' genes influence the attributes of a creature by <this>. '''Dominant''' genes can also be called '''Double-Dominant''', because both parts of the gene are '''Dominant''' parts.* '''Dominant''' genes are notated by a <solid circle symbol> ''in-game'', a <D> in ''text-file notation'', or an <X> when using ''player notation''.  '''Recessive''' genes: '''Recessive''' genes influence the attributes of a creature by <this>. '''Recessive''' genes can also be called '''Double-Recessive''', because both parts of the gene are '''Recessive''' parts.* '''Recessive''' genes are notated by a <empty circle symbol> ''in-game'', an <R> in ''text-file notation'', or an <o> when using ''player notation''. '''Mixed''' genes: '''Mixed''' genes are genes which <do this>. '''Mixed''' genes have a '''Dominant''' and a '''Recessive''' half. '''Mixed''' genes usually behave like '''Dominant''' genes for purposes of influencing attributes of a creature. * '''Mixed''' genes are notated by <target symbol> ''in-game'', a <x> in ''text-file notation'', or a <t> when using ''player notation''. ===== Chromosomes ====='''Chromosome''': A term used to describe a row of genes. Arthropods have 10 '''Chromosome''' rows. '''Group''': A term used to describe a grouping of 4 genes in a '''Chromosome''' row. Arthropods have up to 10 Groups in a '''Chromosome''' row. While '''Groups''' are visible in-game, they are not labeled.* The community of [[Animal Husbandry]] players label '''Groups''' as columns A through J.* '''Half-Groups''' are possible, and Arthropods have 3 '''Half-Groups'''. === How to Read & Write a Genetic Map===To aid communication between [[Animal Husbandry]] players, a system of genetic notation is used which identifies a gene or group of genes through '''Chromosome''' (row) and '''Group''' (column) positions.
Dominant genes: Dominant genes influence the attributes of a creature by <this>. Dominant genes can also be called Double-Dominant, because both parts of the gene are Dominant parts.
* Dominant genes are notated by a <solid circle symbol> in-game, a <D> in text-file notation, or an <X> when using player notation.
Recessive genes: Recessive Genes influence the attributes of a creature by <this>. Recessive genes can also be called Double-Recessive, because both parts of the gene are Recessive parts.
* Recessive genes are notated by a <empty circle symbol> in-game, an <R> in text-file notation, or an <o> when using player notation.
Mixed genes: Mixed genes are genes which <do this>. Mixed genes have a Dominant and a Recessive half. Mixed genes usually behave like Dominant genes for purposes of influencing attributes of a creature.
* Mixed genes are notated by <target symbol> in-game, a <x> in text-file notation, or a <t> when using player notation.
=== Chromosome Terminology ===
The maximum number of genes a creature using the [[Genetics]] system may have is 400. The following examples are all based on [[Arthropod Genetics]], which only uses 238 genes.
 
Chromosome: A term used to describe a row of genes. Arthropods have 10 Chromosome rows.
Group: A term used to describe a grouping of 4 genes in a chromosome row. Arthropods have up to 10 Groups in a Chromosome row. While Groups are visible in-game, they are not labeled. The community of Animal Husbandry players label Groups as columns A through J. Half-Groups are possible, and Arthropods have 3 Half-Groups.
Gene Notation: To aid communication between Animal Husbandry players, a system of genetic notation is used which identifies a gene or group of genes through Chromosome (row) and Group (column) positions.
CR1A4: The identified gene is the 4th gene in Chromosome 1, Group A.
