Interested in getting into the world of Ramathian animals and breeding? This page should explain some of the general basics for you.

==Definitions==
* '''Genes:''' The part of the chromosome that governs the expression of a single trait in an animal (eye colour, fur colour, etc).
* '''Alleles:''' Two alleles make up one gene. When two alleles are present, a dominant allele is expressed and the recessive is not. One comes from the mother, the other from the father. The dominant allele is always a CAPITAL LETTER, and the recessive is always the same letter as the dominant, in lowercase.
* '''Homozygous:''' Has two corresponding alleles for a single trait. Ex) TT or hh ...Etc. Either both dominant or both recessive.
* '''Heterozygous:''' Has two different alleles for the same trait. Ex) Th or Fh... etc. One dominant and one recessive (the dominant allele is always listed first).
* '''Law of Segregation:''' Every one of a persons traits is determined by a pair of genes. Each gene is separated (segregated) into two more parts (alleles).
* '''Law of Independant Assortment:''' Inheritance of one trait does not influence the inheritance of another trait.<br />
* '''Genotype:''' The genetic make-up of an organism.
* '''Phenotype:''' The physical appearance of the trait in an organism.

==Punnett Squares==
For a basic square, you draw boxes that resemble this:

{| width="25%" border="1"
| width="33%" | X
| width="33%" | X
| width="34%" | X
|-
| width="33%" | X
| width="33%" | X
| width="34%" | X
|-
| width="33%" | X
| width="33%" | X
| width="34%" | X
|}

Then, lets say the Genes you're combining are AB for the
father, and CD for the mother. You write in the parents like this:

{| width="25%" border="1"
| width="33%" align="center" |
| width="33%" align="center" | A
| width="34%" align="center" | B
|-
| width="33%" align="center" | C
| width="33%" align="center" |
| width="34%" align="center" |
|-
| width="33%" align="center" | D
| width="33%" align="center" |
| width="34%" align="center" |
|}

Now to combine the genes you first place the genes of the father in the corresponding boxes:

{| width="25%" border="1"
| width="33%" align="center" |
| width="33%" align="center" | A
| width="34%" align="center" | B
|-
| width="33%" align="center" | C
| width="33%" align="center" | A
| width="34%" align="center" | B
|-
| width="33%" align="center" | D
| width="33%" align="center" | A
| width="34%" align="center" | B
|}

Now you place the genes from the mother in the corresponding boxes after the genes of the father:

{| width="25%" border="1"
| width="33%" align="center" |
| width="33%" align="center" | A
| width="34%" align="center" | B
|-
| width="33%" align="center" | C
| width="33%" align="center" | AC
| width="34%" align="center" | BC
|-
| width="33%" align="center" | D
| width="33%" align="center" | AD
| width="34%" align="center" | BD
|}

For many species, you needn't worry about order of the genes.

In the example above if the mother's and father's genes had been opposite what were, they're offspring would still have the same four outcomes, with only
the gene order reversed.

* Gene order doesn't matter in the following species: [[Flitter]]
* Gene order does matter in the following species: [[Trisk]], [[Ficalt]], [[Alugha]]
