Daddy And Mommy Of The Four Bunnies

Thanks for all the responses about "Who's Their Daddy" post yesterday. All the answers are correct: Daddy is a black buck and it's Jamey!

Big Times Jamey's mother Chu's I'm Too Sexy is a chocolate tort and daddy Big Times Armando is a REW. Jamey's color genetics are aaBbCcD-Ee. He is a black, thus aa and B, his mom is a choc tort, thus he gets the choc gene b. He gets his C gene from mom and c gene from dad. He is black, thus D but no information of whether he carries dilute or not. He gets the E gene from dad and e gene from mom. The E gene from dad is not obvious as REW only expresses cc, but since the mom carries ee, the E gene must have come from the dad.

The bunnies' mom is Chu's Valencia, a chocolate tort with a fawn daddy and a chocolate tort mommy. Her color genetics are aabbC-D-ee. Since there is no REW bunny in the litter, probably Valencia does not carry c. There is no information of whether she carries dilute.

Here are the four bunnies from the combination of the above. From left to right, the color genetics of each bunny are:

Tort bunny: aaBbC-D-ee
Chocolate bunny: aabbC-D-Ee
Black bunny: aaBbC-D-Ee
Chocolate bunny: aabbC-D-Ee

To produce the chocolate and the black, it is necessary to have the "E" gene to have the black or chocolate color extended to the rest of the body; and Jamey is the contributor for this important gene.
