When it comes to the genetics of cat coat color when referring to coat color group - refers to (blue, black, cream, red, etc.) and flower color group - refers to (tabbies, fireworks, shades, etc.), if When both of them work, the following general rules will combine coat color/suit color.

1. Male kittens will receive the 2 coat color genes of the female cat, and the children of the male cat will receive the coat color of the female cat (if it is a variegated female cat, it will be one of them). One coat color) or lighten the male cat's coat

2. The young female cat receives one coat color gene from each parent cat, and the mother cat's child will mix or lighten the parent cat's coat color

2.

3. To get a cream or red (coat/color) kitten, the male cat must be cream or red (coat/color) and the female must also be red or cream

4. Only the coat color/suit of the kitten's immediate parents can be displayed on the kitten. Those who appear on the pedigree of the parent's coat/color will not directly act on the kitten. A worthwhile The exception to note is the terminal color gene, which can be shown by carrying several offspring-

5. The kitten's color can come from the parent cat or the mother cat

6. Some major traits (primary coat and flower colors, e.g. fireworks, shades, whites, tabbys, bicolors, etc.) do not skip the previous generation. These traits do not directly affect the next generation without showing up.

8.2 parents of recessive coat color (cream, Blue, etc.) do not breed kittens with dominant coat color (black, red, etc.).

9.2 parents with terminal color will not breed kittens without terminal color.

10. To get a terminal color kitten, both parents must have the terminal color gene (even if they don't show the terminal color).

11. A terminal color cat Mating with a cat that does not have the progenitor gene for terminal coloration will result in kittens with no terminal coloration.

12. A (non-silver) tabby cat, one of her parents Must be shaded or tabby. For a cat with silver and white tabbies, one of the parents must be silver-white tabby, shaded or fireworks.

13. All red cats must have tabby patterns. To say red tabby must depend on whether his parent cat is a parent with tabby patterns or shaded colors. A A red tabby cat, if he is not a true tabby cat, cannot produce a true red tabby kitten unless he is mated with a cat with dominant or shaded tabby.

14. A cat with a white undercoat (firework or shade) must have one of his parents who also have a white undercoat.

15. For a shaded cat, one of his parents must be shaded.

16. A shaded cat can produce fireworks offspring, but a non-shaded (firework) cat cannot produce shaded offspring unless he mates with a shaded cat.

17. Two-color cats must have two-color cats whose parents are two-color cats.

18. Most of the variegated cats (blue-cream, tortoiseshell, tricolor) are female cats, but male cats still occasionally produce (and not all are infertile).

19. A white cat, one of its parents is a white cat.

20. A white cat and a white cat (it can be seen to be white) or and marked Mating for white (not visible white) cats can produce white or marked coat/color. The marked coat/color cat must be dominant, but have a pedigree of white fur. His offspring In planned breeding, offspring of coat color/color can still be produced as expected.

21. Genetically, a single-colored white cat can act on the expected coat color/color of kittens, so that of kittens will be marked with coat color/color.

22.2 long-haired parents do not produce short-haired offspring.

23.2 classical tabby parents do not produce offspring :fish a kitten with a bony, spotted, or spiky tabby. A cat with a spiky tabby pattern must also have a parent with a spiky tabby. A spiky tabby or spot One of the parents of a tabby must be a herringbone tabby or a spotted tabby.

24. The lightening gene must appear in the pedigree of both parents in order to produce a lightening coat.

25. Chocolate and lilac genes, which appear at the same time as the whiskers In the bloodline of both parents, chocolate or lilac cats are produced.
