The breeder should probably not be breeding if he told you that.
Mojave is mostly a pattern mutation, and causes the "cheerio" effect along the sides of the snake, as opposed to the "alien head" effect on most other bps. The color of most mojaves tends to be dark at birth, with yellow markings on the sides and dorsal area. This all fades as they age, but pattern remains the same.
Thank you that’s what I thought ! The breeder I got my girls off of wasn’t the breeder who told me that it’s the breeder I get my rats from. He kinda made me feel stupid for saying it .
