Some people can roll their tongue into a tube shape, while others cannot. Practicing is not likely to help because tongue-rolling is an inherited trait. The allele for rolling the tongue (R) is dominant to the allele for
not being able to roll the tongue (r). Look at the Punnett square on the board, it shows a cross between two
parents with at least one R allele. What letters should be in the two empty boxes for the offspring?
a
RR
С
Rr
d
RRR
