Genetics Question. Otters?

[volchitsa]

Ugh.. I have a short attention span and like surprises... I bred blue tort to a black otter and the black otter kindled today; 5 black and blue otters. I also bred a NZW to a blue otter, and I got 3 white kits and 3 otters. Is the otter trait dominant or something? I really wanted other torties or some variation.
So will this ever happen?
Also, what colors produce chocolate?

Oh and one more thing; how do you get (not buy, from breeding) brokens and agouti, can they just 'pop up' from a different color pattern? Thanks !

The tan pattern is dominant to self, but agouti is dominant to the tan pattern. So, A=agouti, a(t)=tan and a=self.

Think of REWs as a colored rabbit with a coat of white hiding what color it really is, so that rew could be ANY pattern and color under the white. Sounds like your otter buck carries the rew gene, to produce rews, as it is a recessive.

You need the chocolate gene to get chocolates, as it is recessive to black. So, a black carrying chocolate, a blue (dilute black) carrying chocolate, a chocolate or lilac (dilute chocolate), if you bred any two, except blue to lilac, you would get chocolate.

Both Agouti and broken are dominant genes, so you have to have a rabbit with them to get them. A rew could be agouti or broken and you wouldn't know it except by breeding it to a colored rabbit.

Seems your buck is only carrying otter so he will only throw martens and otters unless bred to an agouti and then you'll get agouti colors. You can still make tort otters but they are usually called red or orange otters like the agouti version instead. A red and a tort are the same. One is just a self and the other an agouti. An otter is in between.

If otter is dominant, how did I get a black self? I just looked them over and noticed one was fully black. I don't remember much from genetics class... I'm guessing the mom must be carrying the self trait in order for a recessive trait to be passed like this?
