Document Summary
Cytology and genetics with 30 males and 100 female foxes. Some of the tame foxes were showing signs of proestrus : early and more frequent reproductive status. In the 10th generation, floppy ears appeared in a female pup, as well as a piebald coloration on other tame pups consisting of patches of white and brown on the belly, tail, and paws. A small white star patch appeared in the middle of the forehead of one pup in the 10th generation: tameness as the retention of juvenile behavioral traits, lack of aggression, lack of fear, mild temperament. Increased sociality: longer learning curve, on a microscopic level, one gene control for multiple characteristics or traits. In 1924, several fox farms were operating near new meadows, id: female foxes were selected for breeding on basis of tame behavior and placed in separate nesting communities.
