✪ Tignix Adopts Genetics Guide Part 2- The 'P' gene ✪
The 'P' gene is very similar to the double/single dilution gene seen in horses and ponies and is prevalent in all three subspecies.
✪ Alleles and Phenotypes ✪
There are two alleles in the 'P' gene that code for the double/single dilutions in tignix:
'P'- this is the dominant allele. In its homozygous form a double dilution will occur and in its heterozygous form a single dilution will occur.
'p'- this is the recessive allele. In its homozygous form no dilution is present.
The gene has the following effect on the three base coats:
Double on brown: the coat becomes creamy in colour, the skin becoming a pale pink and the eyes an ice-blue colour (similar to a cremello horse)
Double on green: the coat becomes pastel green in colour, the skin becoming pale pink and the eyes an ice-blue colour
Double on grey: the coat becomes a very light shade of grey (almost totally white), the skin becoming a pale pink and the eyes a very pale blue colour (NB-this is not the same as leucism)
Single on brown: the coat becomes sandy/tan in colour, the skin becoming a dark pink and the eyes an amber colour
Single on green: the coat becomes mint in colour, the skin becoming a pale pink and the eyes a lemon yellow colour
Single on grey: the coat becomes silver in colour, the skin becoming a pale pink and the eyes an ice-blue colour
✪ Allele combinations ✪
P/P= double dilution: brown -> cream | green -> pastel green | grey -> off-white (not leucism, but similar)
P/p= single dilution: brown -> sandy/tan | green -> mint | grey -> silver
p/p= no dilution
