[Dia.]

Username: Dia.
Name: Pallas
Gender: Stallion
Age: 900 Years
Height (can exceed 18 hh): 20 hh
Phenotype: Fleabitten Grey (Flaxen Chestnut) with Blood Marks
Genotype: aa ee ff Gg
Rarity: Legendary
Breeding Notes:
- All foals will at least carry flaxen
- Blood marks are a somatic mutation caused by the dominant G allele turning off in those cells, and won't pass due to the nature of the mutation

Considered Legendary because bloodmarks are considered somatic mutations, correct?
Unsure how you're working with somatic mutation pass rates. I noted that it won't pass, as somatic mutations aren't inherited because the mutations occur in somatic cells, not germ cells. ^^; But I'll change it if you would like!
