The basic genetic makeup of a homozygous Snowshoe cat is: a/a (non-agouti), B/B (black), cs/cs (pointed), L/L (short hair),
S/s (the heterozygous form of the white spotting factor), with variant pigmentation factors (D/D (dense pigmentation) or
d/d (maltesed pigmentation)) depending upon the desired point colors.
The variant pigmentation factors will produce
the following colors/patterns:
B/B, D/D, S/s - Seal point mitted or bicolour pattern
B/B, d/d, S/s - Blue
point mitted or bicolour pattern
B/B, D/d, S/s - Seal point mitted or bicolour pattern carrying the recessive maltesing
In order to produce additional dilute colors, the following basic factors must be introduced:
D/D, S/s - Chocolate point mitted or bicolour
bl/bl, D/D, S/s - Cinnamon point mitted or bicolour
d/d, S/s - Frost (Lilac) point mitted or bicolour
b1/b1, d/d, S/s - Fawn point mitted or bicolour
dominant gene of the white spotting factor (S/S) produces more white than is desirable (more than two thirds white). This
much white would affect the appearance of the Snowshoe which is a result of the contrast between the dark points and the
white spotting pattern.
The mitted pattern is generally limited to paws, belly, chin, and chest with no white facial
pattern, however, small mustache(s)' may be within the mitted limits. The white pattern areas are limited to one third of
the cats coloring.
