Genetics

Genetics are a gameplay feature introduced in Petz 3.

Like real animals, Petz have their own genetic makeup that will be passed on to offspring.

Body
Body inheritance can be broken down into six areas:


 * Ears
 * Head and neck.
 * Body
 * Tail
 * Limbs
 * Paws

Whisker inheritance is not linked to any one body part in particular.

Coat
Color mutations in offspring happen at a rate of about 5%. Only body ballz and addballz mutate; paint ballz can be made to mutate with hexing.

Hexed breeds with "unnatural" body colors that cannot be found in the base game will revert to a white coat. This includes pink Poodles and (hexed) Pigz.

Coat patterns (such as two-tone Sheepdog coloration or Calico patches) are linked to the texture and fuzziness of the body ballz, and one will not pass down without the other.

Outline color on all second-generation and beyond Petz changes to black except for irises.

Coat Markings
Petz can have a maximum of two different genetic sets of paint ballz markings on them. The amount of paint ball markings is controlled by the  in a breed file; it has a value between 0 and 100, with a lower [  indicating a Pet with less markings.

Eyes
There are 104 different eye colors Petz can have.

Eye color mutations frequently happen along the same "spectrum" of color (the 10 consecutive hex number shades), so they may go unnoticed unless breeding from parents with relatively isolated eye colors such as Dalmatians and Russian Blues.

Heterochromia cannot be inherited. Genetic eye color is determined by the color of the right eye, so first-generation Petz with heterochromatic eyes such as Scotties and Great Danes will only pass along the color of their right eye.

Eyelids
The mutation rate for eyelid color is about 4%.

Behavior
Voice and behavior are linked and do not get blended in second-generation Petz.

Trotting is genetic and needs to be inherited; Dogz bred from only non-trotting breeds like Scotties and Chihuahuas will never be born trotters.
