Milk Dipped Ears

So I'm curious about milk dipped ears (white on ears on a broken pattern animal). I have a doe who has a white dipped ear and all three of her broken kits have it. I know she can produce brokens with solid ears. My old herd buck, Luigi had a tiny tiny spot of white under his ear and he produced white dipped ears. Now here is where I am confused- my friend purchased a broken buck whom has solid ears and she bred him to several different does- those does produced milk dipped yet one of those does was a solid and the other broken does had solid ears- so where did it come from? The common link is the buck. My other friend who owned and bred the buck swears it is not his buck as their is zero history of milk dipped ears in his line. But my question is, how can a solid colored doe produce milk dipped ears and why would several other does produce it by the same buck? I'm just trying to know more about the genetics of the milk dipped ears.

Is milk-dipped-ear a well-known thing? I assume this is not the full-on white-ear? Posted Image That is supposed to be semi-dominant so doesn't match your inheritance pattern at all.

From the info you've given my guess is that the milk-dipped-ear trait needs both En and some additional lightening modifiers (of the sort that control the range of spotting from blanket to false charlie) before it shows up. White spotting effects tend to be additive so this sort of interaction would not be a big surprise.

Regarding the solid doe, the absence of En could easily be hiding the presence of genes for milk-dipped-ear.

All of the above is just speculation at this point. Some questions follow. While I'm interested in the answers I doubt they'll lead to any firm conclusion, so answering them all may not be worth your time:
Any pics?
Does the solid doe have broken in its background?
Have you crossed milk-dipped-ear together?
Have there been any charlies with mde sibs or half-sibs? Did any of them show a similar effect?
Are the "several does" with mde kits closely related to each other and/or the buck?
Can you give more complete family trees that consistently include solid and broken with and without mde?

So the doe I just bred is milked dipped herself (see picture below) and when bred to a solid tort, produced milked dipped ears. I do not have a picture of her other ear with the white on it but I posted under her picture a couple of her kits:

Milked Dipped:

My buck Luigi who had the one tiny dot of white on the ears was out of the same line as the doe above.
The solid colored rabbit my friend bred to was not out of brokens but of course brokens were in the line at one time and she did have a few ancestors from the same line as the doe I just posted the picture of but no shared ancestors.

I have not crossed milked dipped together because that would be broken x broken and with the added combo of both parents having milked dipped on top of a charlie- that is a combo (charlie with milked dipped) I do not want to mix in with my line.

So no, no charlies with milk dipped and I haven't gotten to a place for sibling x sibling crossings but will later this fall
The "several" does are not related to each other or the buck and as far as I know, the several does (beside the solid one I bred) do not have a history of milked dipped (but that trait is not noted on pedigrees either)

Because milked dipped (not like the picture you posted but just a term us Holland people use for white on the ears when it should be solid) is not noted on pedigrees (it is a minor color fault for my breed), I couldn't give you a family tree.

not sure if any of this helps you out in any way lol

pet peeve ... really wish broken pedigrees would note these important pattern characteristics - booted, blanket, spot, butterfly, milk-dipped, etc. Depending on breed, they are critical show characteristics and are inheritable (modifiers, most seem more complicated than simple dominant/recessive).

It is always interesting to learn new things. I'd not heard of milk-dipped-ears before. Thanks very much for the extra info.

Yes I am finding their seems to be more genes in factor with the milked dipped. I do wish people would note it on pedigrees. Although it is not my ideal, the dam was just to good of a purchase to pass up. I have seen an older kit out of her from a different sire that was a broken with solid ears so I know it's possible to produce a broken from her with normal colored ears.
