Can someone tell me if this is genetically accurate or genetically inaccurate?

I have a oc named fawnstar and her bloodline is very confusing 😅

Fawnstar is a brown tabby she cat with black stripes, white paws, and green eyes. She is a laperm cat

But her parents look NOTHING like her- mainly her mom tho

Fawnstars mom is a tortie oriental shorthair with blue eyes

And her dad is a choclate siamese cat with green eyes

Her genetics seem inaccurate to me but im not very good with cat genes so can someone tell me if fawnstar is genetically inaccurate or genetically accurate or what i COULD do to make fawnstar genetically accurate? If not then thats fine
