Adult mutations are mutations that don't show until the lion is 2 years old. In the case of Maneless however it can show up at 1 year old but since it is still not visible until then I've classed it under this section as well. Some adult mutations are present only in a certain sex while others can happen in either sex.

Lethal Mutations are, as the name states, mutations that will complicate the lion's life so much that they die early from complications.
