Male cat's chromosome XY(X from mother, Y from father)
The female cat's chromosome XX (one X comes from the mother and the other from the father)
Cat's sex chromosome Y is colorless, only X is colored.
In other words, the color of the male cat XY comes from its mother.
The color of female cat XX comes from father+mother.
Example: A pure red male cat and a pure black female cat.
If the baby is male, it must be pure black.
If it is female, it must be black+red (also known as tortoise shell color)
The picture above shows the hawksbill Garfield.
Example: blue male cat with red female cat.
If the baby is male, or red, or milk.
If the baby is female, the genetic dilution gene is blue+milk, and the non-genetic dilution gene is tortoise shell (black+red).
Another example: a pure red male cat and a tortoise shell color (red+black) female cat.
If the baby is male, it is either black or red.
If it is female, it is either red or tortoise shell color (red+black).
Fade down the gene: on the basis of the cat's true color, fade down the color.
Black faded colors are blue, chocolate and lavender (lavender).
The diluted red color is milky white (also called milky yellow).
If parents carry desalination genes, their children also have a certain probability of carrying desalination genes, and desalination genes have nothing to do with gender.
