Silver Birmans
Silver Birmans
The first thing to establish with Silver Point Birmans, is that colour is a separate entity from pattern.
The following are:
| BASIC COLOURS | |
| DENSE | DILUTE |
| SEAL | BLUE |
| CHOCOLATE | LILAC |
| CINNAMON | FAWN |
| RED | CREAM |
| SEAL TORTIE | BLUE TORTIE |
| CHOCOLATE TORTIE | LILAC TORTIE |
| CINNAMON TORTIE | FAWN TORTIE |
All these colours are possible with any or all of the following:
| BASIC PATTERNS | |
| DOMINANT | RECESSIVE |
| AGOUTI (Tabby) (A) | NON AGOUTI (Non Tabby) (a) |
| Abyssinian (Ta) | Mackerel (T) |
| Blotched (Classic) (tb) | |
| SILVER (Inhibitor) (I) | NON SILVER ( Non Inhibitor) (i) |
| Tipped (high grade) | |
| Shaded (medium grade) | |
| Smoke (low grade) | |
| Dark under colour(i.e. more pigment, less silver) | |
| Medium under colour(more even amounts of silver & pigment) | |
| Light under colour(i.e. more silver, less pigment) | |
| FULL COLOUR ( C) | HIMALAYAN PATTERN (cs) |
| NON WHITE SPOTTING (w) | WHITE SPOTTING (W) |
Unlike colour genes the basic pattern genes will combine with other patterns. This is demonstrated in the Silver Tabby Pt Birman, which exhibits a combination of the four different patterns.
| 1. TABBY | 2. HIMALAYAN PATTERN |
| 3. SILVER | 4. WHITE GLOVING |
Even though the genetic make up may be identical, the appearance of silvers may vary depending on the grade of silver present.
N.B. Silver Tabbies result as a combination of Silver and Agouti (tabby).
Smokes result, when the Agouti gene is absent and the Silver gene present.
