Is it true that you inherit dimples because my mum and dad don't have them and i do?

red hair doesn't help you do anything, neither does blue eyes. mutations are the result of a mistake made in DNA coding, they don't happen on purpose in order to make humans more efficient. sometimes they can be useful and then they will often persist but they don't have to be. if you have dimples and your parents don't that means that they carry the allele but don't display it.
