Coincidence?

I already know this is probably a silly question, buttt totally asking anyways. 😁
Background: Before pregnancy, I never drank pop. If I did by chance it was Sprite. I hated Dr. Pepper, never liked it. My mom and sister never liked it. My husband on the other hand LOVES Dr. Pepper. 
Every since getting pregnant I crave Dr. Pepper constantly!!!!!! 
Does this have anything to do with the child inside me having my husbands DNA and is it affecting my likes and dislikes??? I know, silly, but had to ask.
