It is an albino (or amelanistic, or amel).
It has nice wide borders, too.
Beautiful snake.
My rule is that a snake is automatically female unless proven otherwise.
Unless you are breeding, it doesn't matter (the snake doesn't care!! LOL!)
To sex a snake, if you want to, I would ask around at local pet shops... but make sure that the person actually knows how to sex and isn't just bragging.
Improperly sexing a snake can injure a snake.
I would ask them to sex one of theirs before sexing yours, to be cautious.
Your baby is beautiful... and eats... what more could you want in a snake?
