And if those genes include genes that favor the forced copulation behavior, it will be likely to persist. There is a slight chance that this behavior could inspire more aggressive nipping if one of the rabbits does not cede to becoming subordinate to the other. What is this Jelly-like Blob Under My Dock? In fact, they tend to be easier to manage and less aggressive when there are no females to fight over.
