Colors

[MultipleAnimals]

Hi Yall, so i lost almost all my rabbits to Bloat, so im down to a California Buck and a Black Lionhead Doe(whos supposed to be out of a Black Holland Lop Doe and a Siamese Sable Lionhead Buck, But I Doubt That, This Lionhead Doe is the Same Size as My Buck) What Colors Will I Get Out Of Them? Also, Ill be getting other Rabbits Soon, A Broken Tri Rex Buck(White with alot of red and some Black), A REW NZW Doe, A Cali Doe, and a Black Lionhead Buck. What Colors Would I Get If I Mixed Breeds, Like Rex to Lionhead, or Lionhead to Rex or California to Rex, Things Like That.

The link I am adding will allow you to put in the color of the doe and buck and will generate a list of possibilities for the babies. It even shows the probability of getting that color.

Also, just curious... Do you know how you lost multiple animals to bloat?

No, I dont know how i lost alot to Bloat. I only Feed Pellets unless someone is giving stuff to my animals without permission or talking to me. Which I dont Doubt, We have spiteful Neighbors.

It doesnt show Broken or Tri's.

There is a 50% chance to get a broken from a broken. And Tris are simply broken Harli's. (I can't remember if it shows harli's and I don't know too much about the harli gene)

Oh no, yes be careful of who is feeding them what, I had an aunt try to give mine cabbage last week :/

@HaloRabbits, what's the chances of passing on genetic defects like gastrointestinal by crossing a Charlie buck and broken doe which he sired?

@MultipleAnimals I went back and checked, it does have broken and harli's so you can put in your broken/tri information.
Once you select the base color you look at the genotype at the top. For a broken you change enen to Enen, and for a harli you change the E_ to ej_
If you have a tri then you have to do both of those things.

@Pastor Dave How "broken" is the doe? Do both the doe and the buck have GI issues? IF so, don't breed them. I think Charlies can be great for people raising brokens, but I would not recommend breeding two rabbits with similar 'weaknesses'. Being a charlie doesn't guarantee GI issues but if you know one has these issues then that changes things in your breeding program. The melanocytes (cells that produce color) fail to travel to the gut, most brokens have the color down the back (in many charlies they don't have this). It is best to breed Charlies to solids, because with a Charlie X Broken you will get a 50% chance of Charlies and 50% chance of brokens. With a Charlie X Solid you will get all brokens, so if brokens are your goal, go with that.

To simply answer your question for these two specific rabbits, IF both parents have the issue, you can bet that majority of the kits will as well. IF only the charlie has the issue, you will still get about a 50% chance of the kits having that issue (because they will also be charlies).

The related-ness of the rabbits isn't the problem, it's the broken gene itself. The gene that causes the broken pattern doesn't just affect color, it actually impacts the fetus at a very early stage of its development, when nerves are being formed. The reason that the digestive system of broken patterned rabbits run slower is because they have fewer nerves sending signals to the muscles that line the digestive tract; these muscles contract in a wavelike fashion (a process called peristalsis) and move the food along. Rabbits that have two copies of the gene (Charlies) have considerably fewer nerves carrying those signals than normal, non-spotted rabbits do, so the action of the digestive system is much slower. In addition to a slower system, a lot of Charlies suffer from a condition called megacolon, where the later parts of the digestive tract are expanded to such a degree that the passage of fecal material becomes irregular and may even stop completely at times.

A bit more on the subject of megacolon in Charlies:
