List the different gametes that could be made by a pea plant heterozygous for seed color, seed shape, and pod shape (yyrrii). how large a punnett square would you need to predict the offspring of a self-pollination of this "trihybrid"?

The pea plant can make 8 varying gametes and they are

1. YRI

2. YRi

3. YrI

4. Yri

5. yRI

6. yRi

7. yrI

8. yri

In order to fit all these gametes in a self-pollination, it is required that a punnett square have 8 columns and 8 rows. This would enable it to have spaces for the entire 64 possible unions of gametes in its offspring. Explanation:
