Is there a possibility that my cat could have Siamese in her?

I have a 2 year old cat that looks like blue point Siamese cat, but both of her parents were black American Short hairs. Her body structure is the same as her parent's are, but every time I look at her I think of a Siamese cat. Is there a possibility that she could have part of the Siamese breed in her, and she was born with the markings by chance? I'm just curious about this! :3
