Real Life Animal Gender Benders
Sometimes, this trope occurs in real life.
- Does can grow antlers, though it is rare, and the results tend to be noticeably different from male antlers. For example, they aren't shed at the usual time. This may vary by species.
- Female lions DO get manes- if they are very, very old. It's a hormone thing just like old ladies getting beards. In a similar way, there are also male lions that never get a mane. In fact, there is an entire race of maneless lions. Also, male lions are maneless if they are neutered.
- Peahens with peacock colors have occasionally been reported.
- There are male tortieshell/calico cats, but they either have an extra X chromosome (XXY or Klinefelter's Syndrome), mosaicism, or chimerism. In the former case, the cat will nearly always be sterile, but in the latter two cases, the cat can be fertile.
- There are rare occasions where female narwhals do indeed have tusks
