When a fertilized egg cell divides and comes out as a baby, it is called meiosis, not mitosis.
With mitosis, depending on what cell it starts with, it can come out as skin, or any part of the body (or as part of a plant, or anything else which has cells). Or, as cancer, if the division continues unchecked.
I'm with Astrid in being glad this was mentioned. I'm surprised I never noticed it.
I've been looking at the Devil card today in general and only just noticed the phallic-testicular interpretation a few hours ago.
Before that, I looked at this card and thought, well, there's a column, going through a circle; there's a goat (probably representing Pan), with bizarrely long horns which I've never seen on a real goat (twisted like DNA); and he's got grapes on his head (probably a reference to Bacchus). And a third eye. He seems to be standing on nothing.
Then the two spheres at the bottom- on the left, three women and a child- they seem to be pushing out at the boundaries of the sphere; on the right, three men and some creature- the creature is pushing down two of the men's heads and standing on the other, and the man on the bottom seems to be holding the two others together.
A winged staff with two snakes, but not a caduceus.
Tangled cloudy grey stuff over a pink background.
Pan made it sexual enough, but now the phallic symbolism and the mitosis. Maybe it's about both division and restraint, the sexual and the asexual.
