Questions

Example: to find the probability of a person having light colored eyes (bb) and having the ability to roll their tongue (RR or Rr), multiply the probabilities of those traits

0.09 x 0.71 = 0.0639

Next multiply by 100 to change the number into a percent

0.0639 x 100 = 6.30% chance of finding a person in this class with those two traits.

1.Using your class as a representative population, what is the probability of finding a person who can fold their tongue, has attached ear lobes, and has blue eyes? Show all work.

2. Using the traits sampled in this activity, what is the probability of finding a person genetically like you? Show all work.
