Genotype

Genotype refers to the number indicating how far a racehorse is from its original ancestors.

For example, Z1 through Z10 represent each of the possible Genesis genotypes. These are the most reliable starting points for building out a family line of top performing racehorses. Genotype maxes out at Z268.

When breeding two racehorses together, the new genotype is calculated as follows:

Z XXX of stallion + Z XXX of mare

For example, if a racehorse has a genotype Z12 and breeds with a racehorse that has a genotype of Z35, the offspring will now be a genotype of 47 (12 + 35).

It is impossible to breed a ZED RUN racehorse with a genotype of Z1. The lowest possible outcome for an offspring genotype is a Z2, occurring only when two racehorses, both with genotypes of Z1, breed together.

Genotypes do not, on its own, represent a horse’s ability or a horse’s potential to create top performing horses.
