Mom on the right is half Nubian, and a quarter each Boer and Alpine. Daughter on the left was the result of using a nice La Mancha buck from show lines, perfectly earless.
Mom was exhausted in this picture from gestating triplets, which she had a couple days after it was taken. Daughter is the one I've been writing about recently who had tangled triplets on Tuesday night that Kate (helmstead) helped me untangle.
If you breed a purebred LaMancha with gopher ears to a Nubian, you usually get elf ears that are on the long side compared to LaMancha crossed with Alpine style ears. If it's an elf-eared LaMancha, you could get elf, airplane, or Nubian ears depending on where the LaMancha got its elf ears.
