✪ Tignix Adopts Genetics Guide Part 6- The 'Pr' Gene ✪
This particular gene codes for markings similar to the primitive dun markings as observed in many equines, hence the gene's nickname: 'primivia.'
✪ Alleles and Phenotypes ✪
There are two alleles in the 'Pr' gene:
'Pr'- this is the dominant allele. In both its homozygous and heterozygous form the base coat becomes slightly lighter (though it can be harder to tell in the double dilutions) and darker markings will form, including eye rings, ear markings, dorsal striping, paw markings, tail tips and banding on the lower legs and tail.
'pr'- this is the recessive allele. In its homozygous form no markings are present.
✪ Allele combinations ✪
'Pr/Pr'- the 'primivia' coat is present
'Pr/pr'- same as above
'pr/pr'- no changes to the base coat
NB- The expression of this gene is masked completely by both dominant alleles of the 'A' gene.
