(b) "If you have straight hair, then both of your parents must carry an allele for this trait, although it is possible that neither of them actually has straight hair."
Provide a detailed explanation of each statement, being sure to explain the process by which each trait is expressed and how, if at all, the trait of tongue-rolling and the trait of straight hair are different.
