Consider These Statements from the Text

Essay

Consider these statements from the text:
(a) "If you can roll your tongue lengthwise into the shape of a tube, then at least one, but not necessarily both, of your parents must possess this . . . talent."
(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.
