The horse is genetically negative for the pearl allele, meaning it does not have any copies of this genetic variant. Its phenotype reflects the natural, unaltered base coat color. This horse will not pass the pearl dilution trait to its offspring, ensuring the continuation of the base coat color in the lineage.
- N/Prl –Positive Heterozygous
The horse is positive for the Pearl allele in a heterozygous state, indicating it carries one copy of the pearl variant. This configuration subtly dilutes the base coat color, infusing it with golden tones, although in some instances, the dilution effect may not be visually apparent. As a heterozygous carrier, there's a 50% probability that it will transmit this dilution trait to its offspring, potentially leading to varied coat colors among the progeny.
- Prl/Prl - Positive Homozygous
The horse is positive for the pearl allele in a homozygous state, carrying two copies of this genetic variant. This genotype manifests in a more noticeable dilution of the coat color, even in the absence of other dilution genes. Being homozygous, the horse will invariably pass the pearl allele to all of its offspring, ensuring the trait's propagation and contributing to the diversity of coat colors in future generations.
