You have a striped California king snake.

Stripe is dominant to the normal version of the gene. In other words, if the snake has two normal genes, the snake is the normal, banded pattern. If the snake has a striped gene paired with a normal gene, the snake is striped or some variant of the striped pattern, such as broken stripe, dot-dash, or a mix of stripe and bands. If the snake has two striped genes, the snake is striped or some variant of the striped pattern.
