What mix am I?? Labrador and... Yorkshire??

Hi, I just found this forum and would like to know what people think of my little puppy.

She's 15 weeks old right now and is a very good pup We bought her from a guy we didn't know and he told us she's Labrador and Yorkshire (which didn't seem to make sense to us lol) we saw the mother and she's a 40lbs black lab so we know for sure she has Lab and she looks like a lab, now our vet says he doesn't think it's possible for the dad to be a Yorkshire... but for sure the dad is a very tiny dog because at 15 weeks old she's only 12lbs and according to the growth chart she will be between 20 and 25lbs full grown.
