Unusual coloring, even for a tortie. Kaylee has a split face right down the middle. Bet her DNA shows she came from two dads. A bundle of everything in one.
A girl kitty doesn't get any color DNA from her father (with the possible exception of white); the gene for red or black is located on the X chromosome,in the section that is not on a Y chromosome. Tortie and calico have one X with the red gene and one X with the black gene.
As for grey and ginger -- those are black and red (respectively) with the addition of a "dilute" gene.
