1. Count out 60 black beans and 40 white beans into the baggie. Let the black beans represent the dominant allele A, and the white beans represent the recessive allele a, in the gene pool. This is your F0 generation. 2. Without looking, randomly remove two beans from the baggie. This represents one diploid individual offspring in the next (F1) generation. Tally the diploid genotypes of the offspring formed by these two gametes in Table 1 below. 3. Return the two beans back to the bag and gently shake it to reinstate the random gene pool. By returning the beans after each selection, the size of the gene pool remains constant and the probability of selecting any allele should remain equal to its frequency in the gene pool. Repeat this 50 times, meaning 50 individual diploid organisms. 4. Make sure to return all beans to the baggie. 5. Repeat this procedure (steps 2-3) (for your F2 generation) until you have recorded the genotypes of another 50 individuals.
