Problem: A homozygous yellow pea plant (YY) is crossed with the homozygous green pea plant (yy). You will now add a second trait. The texture of peas is also controlled by one gene. The dominant trait is smooth (S), and the recessive trait is wrinkled (s).

Identify the four possible gametes produced by pea plants with the following genotypes:

Pea Plant #3: YySs

Pea Plant #4: YySs

Required:

1. Make a Punnett square for the Part 2 dihybrid F2 cross between Pea Plant #3 (YySs) and Pea Plant #4 (YySs).

2. What are the phenotype ratios for the F2 generation?

3. Make a data table to display your results from part 2 of the experiment. Your table should include genotype, and phenotype for all 16 attempts in both trials.

4. What are the phenotype ratios for Trial 1? For Trial 2?

5. How do the experimental phenotype ratios compare to the expected ratios from the Punnett square?

6. What would you do to increase your chance of getting experimental data that are closer to the predicted data from the Punnett square?
