Basic Color Genetics

Tool Note: If your sphynx sire or dam also has white spotting, then just choose the base color and know that even if one parents is bicolor, then the litter may also include bicolors.

Below is some basic information on color genetics.

All cats are basically either black or red and some also carry other genes which change the appearance of those colors.

Some of those other genes are:  
“Dilute” - The dilute of black is blue. The dilute of red is cream.   
"White" - Covers or hids the true color of the cat.  White is NOT a color.
"Tabby (Agouti)" - All colors can be combined with a tabby pattern, with or without white.
"Pointed" - Limited color on body and rich color on cool areas - eyes turn rich blue.
"Mink" - Similar to pointed but darker body and less contrast between body and points -  eyes typically turn aqua.
"Sepia" - Rich color midway between that of a point and traditional - eyes typically turn green.

"Chocolate" Rules
1) It is impossible to produce a chocolate sphynx if only one parent carries it.
2) In order to produce a lilac sphynx, both parents must carry chocolate AND dilute.

"Sex Linked Red" Rules
The term "red" refers to "red" or "cream".  Cream is the dilute of red (both parents need to carry diulte to produce cream.)

1) If you don’t see red or cream on one of the parents, there won’t be red or cream on the kittens.   
2) Reds almost always look like tabbies as kittens - even on genetic solids (without the agouti gene.)
3) If the sire is red/cream ALL FEMALE progeny will be tortie/torbie or red/cream

"Thermal" Rules
Remember, each cats is carrying 2 of these genes, a phenotype and genotype.  So DNA test your cats color so you know what they are also carrying (the gene you can't see.)

1) Point x Point = Points
2) Sepia x Sepia = Sepias
3) Mink x Mink = Minks, Sepias, Points
4) Point x Sepia = Mink
5) Sepia x Mink = Sepias, Minks
6) Point x Mink = Points, Minks, Sepias
