The ability to roll your tongue is dominant (R) to not being able to roll your tongue (r). Grandpa Jones is a tongue roller but Grandma Jones is not. They have four children (2 sons and 2 daughters), one son cannot roll his tongue, but the other 3 children are all rollers. Their last daughter, Judy, married John Smith.
