: I'm at a loss to fully explain my recent breedings of German Tuxedos.  I have however, developed a preliminary theory based on my current observations.

: Let's take two fish, a white tailed tuxedo and a female tuxedo.
: The male is phenotypically "White" and we'll assume that his genes are "White & Yellow".  Let's breed that to a female whose genes we'll assume are "Yellow & White".

: Note: If the female were to display color she would be yellow as that gene is presented first.

: The offspring then will be of these genetic types:
: 1)  White/Yellow
: 2)  White/White
: 3)  Yellow/Yellow
: 4)  Yellow/White

: Now, here's the theoretical part:  If the genes are mixed as in examples 1 and 4, the color of the female parent takes precedence.  In this case fishes 1 and 4 would be yellow (as their mother was yellow).  Fish 3 would be yellow.  Fish 2 would be white.

: The genes of the fish then become respectively:
: 1)  Yellow & White
: 2)  White & White
: 3)  Yellow & Yellow
: 4)  Yellow & White

: The phenotypical color of the fish would be the gene which is listed first.

: This is my current theory that I'll be testing.
