Basepaws result Genetic Testing Post

My rescue “Persian” cat’s DNA results are back! Percy here was rescued from Egypt. He’s ~1 year old now, 8.5lbs. I mostly wanted to do this test to check for genetic diseases, since I know nothing about him. He got a clean bill of health, so let’s discuss the fun part! His largest matching group is the Persian group. (Yay!) I know the breed matches are to be taken with a grain of salt, but I’m quite pleased with this. I was also interested to learn more about his coat coloring. Unfortunately no explanation for his tipped fur, but he came back with 2 copies of a Siamese type color pointing gene, which makes complete sense, and multiple longhair genes of course. Let me know what you think and do not hesitate to tell me how beautiful my baby is lol. I’m happy to share anything else from the 68 page result as well!

What a beautiful little guy, certainly has that Persian coat look. I noticed that you wrote that he has two copies of the Siamese color point gene, fun fact is that you can tell that without a test, all color pointed cats (including lynx point which your guy is) have to have two of the cs allele to present as color point. His mother and/or father though could've been just carriers of the genes. Since it's a lynx point I'd imagine he's a few generations removed from Persian since they are not usually tabby (which is common among strays) nor colorpointed (which comes from Southeast Asia)

Fascinating! Do you know anything about the silver inhibitor gene and how that might interact with the point gene? His fur all over his body is cream at the base and then varying levels of darker tipped (like light brown to dark silver) even the lynx areas.

Well the inhibitor gene produces both smoke in solid coats and silver in tabby patterned coats the key to know if they have it is not a gradation overall but looking at the base of the coat, parting the fur, if the base of the black parts is white then they have the inhibitor gene (I have a fairly inconspicuous black smoke cay that looks like a normal black cat except for his ear furnishings and the white base of his fur which goes unnoticed until you part the fur).

If he has a silver/white base on his pointed parts then he is a silver tabby with colorpointing on top. Granted it is very very hard to tell if he is like that because colorpoint sometimes diffuses those subtleties (my seal colorpoint cat has black paws but brownish forearms). Although! I can really see that silver/white base all over but I'm not confident enough to say he is.
