Ticked-

stripes on legs and tail

Spotted-

stripes on legs and tail

with “leopard spots” on body

coat color patterning white spots

Gene for absence of color- spotting factor S

SS- more white

Ss- ventral white

ss- no white4

Coat color patterning- white spots

Tabby: ticked>mackerel>classic

Gene Codes
other genes

There are also other genes that account for points, like a Siamese cat- head, feet and tails darker color

Mutations that cause long hair

Some suggest that many of the white genes are additive

There are many different names for all of the cat genes, and some are just suspected genes…

This does not make any sense in normal mendelian genetics, becaseu tomcat would not be possible. I think the mother must be hetero for S, and be mosltly white because of other gene affects.

errors

Some sources think the white genes may be additive, so there may not be a clear cut between ventral white, <50% and white with spots, >50% as thought.

The queens at the main feral colony are all related-either sisters or mother/daughter. There are 1-2 white queens with black spots, 1-2 white queens with grey spots, without knowing that I should have been looking at striping patterns too, some may be black tabby…. Which may look grey from afar.
